Blink (TV story)

Blink was the tenth episode of series 3 of Doctor Who. Based on an earlier short story by writer Steven Moffat, Blink introduced the Weeping Angels.

It was also the second "Doctor-lite" story in BBC Wales Doctor Who, having come about out of a need in the production schedule for double banking.

Moffat had intended to write a two-parter earlier in the series but was too busy writing and executive producing. Believing he had "messed everything up", Moffat offered to "throw [himself] onto the grenade of the unpopular episode", referring to the Doctor-lite concept. In a 2008 interview, he admitted that he had only just started realising that Blink was in fact "a really great episode". Because of its late submission, Blink was the quickest piece of writing Moffat had ever done, having gone straight from the second draft with no notes to the script and tone meetings before going into production ten days later. The scriptwriting process took such little time to produce that Moffat claimed that Blink was such a "tiniest sliver" of his writing career that he couldn't remember making it.

It has since received mass critical praise. In DWM 474, Blink was rated #2 by fans, among the very best television stories in Doctor Who's then-50-year history.

Synopsis
In an abandoned house, the Weeping Angels wait. The only hope to stop them is a young woman named Sally Sparrow and her friend Larry Nightingale. The only catch: the Weeping Angels can move in the blink of an eye. To defeat the ruthless enemy — with only a half of a conversation from the Tenth Doctor as help — the one rule is this: don't turn your back, don't look away and don't blink!

Plot
Young photographer Sally Sparrow breaks into an old house (Wester Drumlins) and takes photos of fallen chandeliers and moss growing in fireplaces. Entering a room upstairs, she sees peeling wallpaper and the letters "BE" exposed underneath. She pulls back the corner and finds the message "BEWARE OF THE WEEPING ANGELS". She tears off more wallpaper, revealing a message telling her to beware of the Weeping Angels, and telling her to "duck, Sally Sparrow." It is only when she reveals the words "duck now" that she actually does so, narrowly avoiding a rock that would have hit her head. She looks out the window, from where the rock was thrown and sees the statue of an angel with its hands covering its eyes. She peels the rest of the wallpaper off to reveal the writer of the message — "Love from the Doctor, 1969."

Sally appears to return home, looking into her living room; there are numerous televisions; they show a man with glasses, although, on one screen, a young woman is butting into the scene. The man tells the viewer not to turn away, not to look away, and not to blink — "Blink and you're dead." Sally calls her best friend Kathy Nightingale, despite the late hour; she answers, groggily, but refuses to leave her home.

It's then revealed that Sally is in Kathy's home, having been given a key. Annoyed, Kathy gets ready to greet her friend; however, upon hearing the toilet, Kathy asks if Sally has met her brother, warning her that she's about to. Sally turns to the hall to see Kathy's naked brother, Larry, who desperately hoped he was wearing pants. Kathy walks in, shouting at Larry to get to bed; she then notices Sally isn't concerned by this, asking her what's wrong.

The next morning, Kathy and Sally return to the house; Kathy has a laugh that they are acting like detectives. Sally shows Kathy the message on the wall and the Weeping Angel but thinks it is now closer to the house than before. Someone rings the doorbell; Sally answers it, and Kathy waits in the room where the writing on the wall is - "in case of incidents". Sally answers the door to discover a man who is looking for her. He says that he was told to come to this place on this exact date and time and give Sally Sparrow a letter. As Kathy spies on the conversation from in the room, she fails to notice the Weeping Angel moving whenever it isn't in sight; lowering its hands from its eyes, and creeping into the room and upon Kathy from behind.

When Sally asks the man who sent him, he replies that it was his grandmother, Katherine Wainwright, who specified that he explains that before marriage, she was known as Kathy Nightingale. At that moment, the door to the room Kathy is in slams shut. Sally calls to Kathy, which the man assumes is her wondering if he said the right name; he restates her full name, Katherine Costello Nightingale. Sally presumes she has figured out the joke and calls for her friend, but Kathy does not answer. When she goes back into the room where she left her, Kathy has completely vanished, and the Angel is back in its original spot and position outside.

Elsewhere, Kathy gets up in a field and asks a local lad where she is. He replies that she is in Hull, but she refuses to believe it until he shows her the local newspaper, which not only confirms her location but also shows the year to be 1920.

Back at Wester Drumlins, the man has become upset; he promised to fulfil this task for his grandmother, Kathy Wainwright, who died in 1987. This persuades Sally to take the letter, who reads it; this man is indeed Kathy's grandson, who swore to fulfil her last request. In anger, Sally flings down the letter and heads upstairs, only to find three more Weeping Angels. One of them has a Yale key in its hand. She takes it and heads out, only to find Kathy's grandson leaving with his promise fulfilled. As Sally leaves, she fails to notice the Angels uncovering their eyes and watching her as she takes the key and leaves.

In a coffee shop, Sally reads the letter fully, learning Kathy led a full and happy life, with Ben, the first person she met in Hull with a family. She includes photographs of her and her children (with her daughter named after Sally), and grandchildren. Sally reads Kathy's joke about living to an exceptionally old age and her request to tell Larry, who works at a local DVD shop, something; her parents are gone by this time, so he's really her only close family. Sally goes to Kathy's grave to pay her respects to her dead friend (having a laugh that Kathy lied to Ben, claiming to have been younger than she was), then leaves for the DVD shop. Sally fails to notice one of the Angels from Wester Drumlins spying on her in the graveyard.

When Sally gets to the DVD shop, she goes into the back to find Larry. She, unconvincingly, explains to him that Kathy has had to go away due to work and that it's nothing to worry about. She also honours her friend's request to tell her brother that she loves him. Larry smiles at that and then wonders if that's an indication that something is wrong with her or whether it is all just a joke but Sally assures him that everything is fine. She sees the man with glasses who was giving the blinking warning on the screens in the Nightingale's flat on a TV which Larry has been studying. He explains that the man is an Easter egg found on seventeen DVDs and no one, not even the manufacturers or the publishers, knows how it got there. He simply sits there and makes random remarks; it's like listening to half a conversation. Larry and his internet friends have been constantly trying to figure out the other half. As he and Sally are talking, the DVD keeps un-pausing itself, and the man with glasses continues with his random phrases, two of which fit with Sally comments; much to her shock. In the end, Larry gives her a list of the seventeen DVDs that have the Easter egg on them. She leaves the shop, having gotten an idea from a comment said by Larry's co-worker ("Why does nobody ever just go to the police?") about what to do next.

Sally goes to the police station, and mentions the house's name. While waiting, she sees two of the Angels on the church across the street. While watching them, she blinks and they have disappeared. She doesn't see that they are now above the window she is looking out of. She then meets DI Billy Shipton. He shows her a collection of cars with something strange in common: all of them were found outside the Wester Drumlins house (some with their motors still running) and all of their owners vanished without a trace. He shows her a fake police phone box, with a lock that will not open. Billy charms Sally to give him her mobile number before she leaves. After she leaves, Billy finds the Weeping Angels have appeared in the room with him, surrounding the phone box. While examining them closely, he blinks.

Outside, Sally finds the key she took from the Angel's hand in her coat pocket. She heads back to the garage to try it out, but Billy and the police box have gone, and the outside door is broken. Someone has broken through it with great force.

Billy gets up to see the Doctor and Martha, who tell him he is in 1969, because of the "touch of an Angel"; most likely the same one as he is in the same year that they are. The Doctor advises him not to go swimming for an hour as time travel without a capsule is disorientating. He remarks that the Weeping Angels are the only psychopaths that "kill you nicely"; they send their victims into the past and feed off the days they might have had. Billy does not understand any of this but Martha advises him to nod when the Doctor stops for breath. The Doctor explains to Billy how he found him by showing off his Timey-wimey detector - a modified lunch box, which detects when someone comes from a different time - "and can cook an egg from 20 paces, whether you want it to or not." Because of this, he actively avoids chickens, as it's not pretty when they blow up. The Doctor explains that normally, he would have offered Billy a ride home; however, someone's nicked his motor. After they talk, the Doctor asks Billy to give Sally Sparrow a message and apologises that it will take "a while" to get the message through.

Back in the present, Sally gets a phone call. She goes to visit an old and dying Billy at the hospital. They have a laugh that Billy managed to marry a Sally, who has already passed away. Billy goes on to explain that he often thought of contacting her before tonight, but says it would have "torn a hole in the fabric of space and time and destroyed two thirds of the universe." She asks where he got that from and he replies there was a man he met in 1969 called the Doctor who asked him to pass on a message to her - "look at the list". She is not sure what this means and he says that it's a list of seventeen DVDs. Billy reveals that he didn't stay a policeman back in the '70s; he instead got into publishing, then videos and eventually DVDs. Sally realises that he was the one who put the Easter eggs on the DVDs. She is curious as to how the Doctor knew she had the list considering she has not had it long. Billy replies that he asked the Doctor but he couldn't tell him; only saying that she would understand one day, but that he won't. She offers to come and tell him once she has figured it out but he solemnly says that the Doctor told him that this would be their last meeting before he dies. She decides to stay with him until the end. He thanks her and says he only has until the rain stops.

After the rain has stopped, Sally calls Larry. She has realised what the DVDs on "the list" all have in common: they are all owned by her; specifically, they are the only DVDs that she owns, which means that the Easter egg is meant for her though he is more shocked by the fact she only owns seventeen DVDs. She ignores this and asks him meet her at Wester Drumlins and to bring a portable DVD player.

Larry does so and brings two copies of the DVD. One has a slightly better picture but he opts for the one with the best sound. They play it and see the full message from the Doctor. He makes the same random comments from the video store, but now they fit perfectly into what Larry and Sally are saying. Realising this, Sally thinks he can hear them, but Larry explains that he always says it and that he has got a transcript of the Easter egg with him. As the Doctor gives his message, everything Sally says seems to fit in, so Larry, now very excited, begins to add her words to the transcript.

The Doctor mentions that he has a copy of the transcript on his autocue. That is how he knows what she is saying. He warns of creatures from another world, the "Lonely Assassins", aka the Weeping Angels. They are incredibly fast, and they can send people back in time, which is how he got stuck in 1969. These aliens have a unique defence mechanism: they are "quantum locked"; they do not exist when they are being watched. If any living thing looks at the Angels, they immediately turn to stone until they are no longer looked at. This explains the "weeping"; they cannot look at each other since it has the same effect. "Their greatest asset is their greatest curse". They are looking to get into the TARDIS, which contains a world of time energy, which the Angels could feast on forever but the damage they could do could switch off the sun. And since Sally has the key, the Angels are after her now.

The Doctor is stuck in 1969, so he is relying on Sally to send the TARDIS back to him. When she asks how, he states that he has run out of transcript, but he can guess why: he surmises that the Weeping Angels are closing in, forcing her to flee and so left the transcript unfinished. Indeed, Larry has stopped writing. He says what Sally has already heard; she must keep her gaze on the Angels; she mustn't turn away, look away, or even blink – the Angels can move with incredible speed when unobserved; "Blink and you're dead." Once the message has ended, Sally screams for the Doctor not to go so Larry offers to rewind it but that would be of no use. They both realise at the same time that neither is looking at the Weeping Angel anymore. They look up. The Angel is now in the room with them, baring sharp teeth in a savage snarl and outstretching clawed fingers towards them.

As a terrified Larry keeps his eyes fixed on the Angel to stop it getting any closer, Sally searches for a way out. As she tries all the doors in the house, only to find the Angels have locked them in while they were watching the Doctor's message, Larry is growing increasingly restless and fearful that the other Angels could come up behind him. Larry turns around for a split second, and the Angel moves to right in front of him. Keeping his eyes on it, he slowly backs out of the room. Sally finds an unlocked door to the cellar, and calls out to Larry to give him the news. Larry willingly flees to rejoin with Sally.

Larry and Sally descend into the cellar to find a way out. They find the TARDIS, along with the other three Weeping Angels. They head towards the door, keeping their eyes on the Angels. As they get to the TARDIS, the fourth Angel has appeared by the stairs and is pointing at the light. The light starts to flicker, and Sally and Larry realise in horror that the Angel is draining the light so that the Angels will be able to attack in the darkness. With each flicker, the Angels move towards Sally and Larry with their claws out and their teeth showing, as they frantically try to unlock the TARDIS door. At the last second, they open it and flee inside and lock the Angels out just in time.

As the two look around at the TARDIS interior in amazement, a hologram of the Doctor activates and says that the TARDIS has detected an authorised control disc, valid for one journey only. It is the other copy of the DVD that Larry brought, which is now glowing. But the Angels outside begin shaking the TARDIS on each side, looking for a way in. Larry puts the DVD into the console and the TARDIS begins to dematerialise. But as the TARDIS begins to fade away around them, Sally realises the TARDIS is leaving, but she and Larry are not going with it. She screams at the Doctor to help them, even as the TARDIS fades, leaving them crouching in the middle of the circle of Angels. Sally yells to keep looking at them, but Larry stands up slowly and realises that the Doctor tricked the Angels - they've been left looking straight at each other, freezing them permanently.

A year later, Sally and Larry are running the DVD store together but Sally cannot let all that has happened to them go as she still doesn't know how the Doctor got all the information he possessed. Sally is shown to now have everything she recorded, including the transcript, the photos of the wall and the list of DVDs in a folder which she keeps on her at all times. Larry subtly hints that her obsession with this is preventing them from having a relationship but she insists that they merely run a shop together. He then goes out to get some milk. Sally then glances outside as a taxi pulls up and the Doctor and Martha get out. She rushes over to talk to them, only to find that the Doctor doesn't recognise her as the events of her past are still in his future. Sally suddenly realises that she is the one who gives the Doctor the information he needs to retrieve the TARDIS and save her from the Weeping Angels. Sally then hands over the folder telling him that, at some point, he's going to be stuck in 1969 and he'll need to ensure he has it on him when he is. The Doctor is in a rush, still in the middle of another adventure, but asks Sally's name and tells her its nice to meet her. Larry returns right at that moment with the milk and can only stare at the Doctor and Martha in stunned amazement. The Doctor is in a hurry and cannot stay, so he and Martha eventually head off to take care of "four things and a lizard", while Sally clasps Larry's hand and goes back into the shop, Sparrow and Nightingale's antiquarian books and rare DVDs.

However, the scene shifts to montage across the public statuary, punctuated with the Doctor's recorded warnings, as though to warn us that there might be other Angels lurking among the statues...

"Blink and you're dead. Don't turn your back. Don't look away. And DON'T. BLINK. Good luck."

Story notes

 * This episode, like series 2's Love & Monsters, is a Doctor and companion "light" episode. The Doctor and Martha were purposely not featured in this story so David Tennant and Freema Agyeman could concentrate on the final three episodes of season three.
 * This episode won a Hugo Award in 2008.
 * The plot of this episode was based upon a short story Steven Moffat wrote for the Doctor Who Annual 2006 called What I Did on My Christmas Holidays by Sally Sparrow. The story involves Sally Sparrow (who is a child in the story as opposed to a young woman in the episode) writing her school assignment about being contacted by the Ninth Doctor through photographs and a videotape (like the episode, there is a sequence in which Sally has a conversation with the Doctor through a television) in which he gives her instructions to allow her to return the TARDIS to him (the Weeping Angels aren't present in the story; the Doctor being separated from the TARDIS was due to a "hic-cough"), knowing what to do thanks to an adult Sally (who is a beautiful spy who saves the Doctor's life) giving him the story which details the experience.
 * The story is ultimately an ontological paradox: the Doctor has all the information, the transcript of the conversation, the contents of the message behind the wallpaper, etc, because Sally gives him that information at the end of the story — but Sally gets that information from seeing the wall the Doctor wrote, watching the DVD the Doctor made and so on. The information never really "starts" anywhere — the Doctor knows what to say in the conversation because he's reading Larry's transcript, which Larry made thirty-eight years later by watching the conversation. The information is in an endless loop.
 * Despite only appearing in cameos, David Tennant and Freema Agyeman are still credited as the main stars rather than Carey Mulligan in the episode's main role of Sally Sparrow.
 * Banto's DVDs were fake titles created for the episode, complete with DVD covers and poster designs.
 * This is the first episode to be directed by a woman after a twenty-two-year interval. The previous one was The Mark of the Rani.
 * When Larry brings Sally the list of DVDs, a vintage White Star Line sticker can be seen stuck to the back of the folder; Titanic, the most famous White Star vessel, would later inspire the setting for Voyage of the Damned.
 * For reasons unknown, while the original BBC One broadcast and subsequent Region 2 DVD release of the episode includes a "One year later" on-screen graphic prior to the epilogue scene, broadcasts of the episode in North America, as well as Region 1 DVD release, omit this.
 * In 2009, Doctor Who Magazine conducted a reader poll to rank the first 200 Doctor Who stories in order of preference. Blink ranked 2nd, surpassed only by the 1984 story The Caves of Androzani. A similar poll was run in 2014, with Blink again coming second overall, this time beaten by The Day of the Doctor. In 2023, it was revealed to have been ranked as readers' favourite Tenth Doctor story in all three of their major polls held since its airing. (DWM 592)
 * Billy can be seen in the police station with a patch on his jacket depicting a sparrow, a possible joke on the main character's last name.
 * A sequel to this story, A Ghost Story for Christmas, was released as a webisode on Day 24 of the 2009 Adventure Calendar on the official Doctor Who website. It was narrated by John Barrowman as Jack Harkness in the style of a ghost story and depicted the abduction of another woman by the Weeping Angels.
 * The concept of the Doctor's first encounter with someone also being that person's final encounter with him would later be significantly expanded upon with the character of River Song.
 * The story was originally titled Sally Sparrow and the Weeping Angels, but Russell T Davies didn't like the title. Steven Moffat suggested Blink as an alternative, which Davies loved, but wanted the word "Blink" in the script "like a cheesy 50s trailer".
 * Rather than being inanimate props, the Angels were portrayed by real actresses covered in make up and prosthetics. But standing completely still is a great challenge even for the most accomplished of actors. It was revealed on the DVD commentary that a special digital effect was used to freeze them in place so that if they did involuntarily move, it wouldn't be noticed.
 * Steven Moffat originally had a different, and much darker, ending in mind for this episode. It would have seen Sally give the Doctor the folder and then step back inside the store to find an Angel inside. Larry then steps in and notices that Sally is not there. He then looks more closely at the painting on the wall and realises the person smiling and waving in it is Sally, having been sent into the past by the Angel. After reflecting on the episode for its 10th Anniversary, Moffat stated that "It makes me wonder why an Angel never sent her back in time. All these years later, I wonder why I didn't end it like that."
 * Billy Shipton comments that the police box isn't a real one as, "the phone's just a dummy, and the windows are the wrong size". This is a reference to the fact that the TARDIS props over the years have been scaled down versions of the real thing.
 * One humorous deleted scene would have formed part of the pre-credits teaser. After Sally discovered the message behind the wallpaper, Steven Moffat had requested the sound of cliched horror movie music. This would turn out to be Sally's mobile phone ringtone, and it was actually Kathy calling her friend from a pub.
 * Steven Moffat initially wrote placeholder dialogue in the script for the scene where the Doctor tells Sally that he can hear her in the DVD shop, because he knew the lines that appeared would have to play "double duty later on" and be authentic and fresh both times.
 * Steven Moffat claims that the Weeping Angels were inspired by the children's game 'Statues', which he found "frightening".
 * Steven Moffat revealed that Carey Mulligan was offered the chance to stay on as a companion, but she declined.
 * The scene wherein the Doctor talks to Sally via a DVD extra was created by writing a conversation, removing Sally's lines, then having David Tennant record his lines. Steven Moffat felt that this one-way filming made the performance more convincing.
 * To create the rigid structure of the angels' dresses, prosthetics supervisors Rob Mayor soaked fabric in fibreglass resin, which was then painted over.
 * To create the effect of the Angels rocking the TARDIS, Carey Mulligan and Finlay Robertson threw themselves around the ship's set. The camera's operator then shook the camera in the opposite direction that Mulligan and Robertson threw themselves.
 * At one point, Sally would have been seen to be pregnant at the episode's conclusion, but Steven Moffat decided that it was more effective to delay Sally and Larry's romance until after her meeting with the Doctor.
 * Steven Moffat had held the idea of the Weeping Angels since seeing an angel statue in a graveyard whilst on a family holiday to Ickworth, Suffolk where the hotel had been close to a condemned churchyard and cemetery.
 * Originally, the producers considered having Michael Obiora play both the young and old version of Billy Shipton. However, it was decided that Obiora in makeup would look too fake, and so Louis Mahoney was cast to play the older version.
 * In a 2017 interview for the episode's tenth anniversary, Finlay Robertson mentions that he had to change his accent to match Lucy Gaskell's, as their characters Larry and Kathy are siblings.
 * Michael Obiora and Louis Mahoney played father and son in the series Sea of Souls.
 * The first draft of the script is very close to the finished episode with the exception of the ending. Instead of taking off by itself, the TARDIS brings Sally and Larry to 1969 where they meet the Doctor and Martha. After returning them to the present, the Doctor reveals that he learned everything from a book called Sally Sparrow and the Weeping Angels. He asks Sally to sign it and she sees that the author's name is Sally Nightingale. Also, Kathy was originally named Jenny.
 * A scene cut from the epilogue had Larry revealing that he regularly checks to ensure that the Weeping Angels are still petrified.
 * David Tennant suffered from voice problems during this story.
 * Exploding eggs are mentioned twice - once by the Doctor about his device that has a side effect of boiling eggs and exploding hens, and also by Larry who says that having a complete transcript of the Doctor's DVD extra would "explode the egg forums".
 * Finlay Robertson named Larry Nightingale as his favourite televison role on Twitter in 2023.
 * For a time, Steven Moffat struggled to devise a way for the Weeping Angels to be defeated. The ultimate resolution was suggested by Mark Gatiss, taking advantage of Moffat's intention to include several Weeping Angels in the narrative.
 * The episode was originally intended to form the season's sixth production block. When it was decided to move up the recording dates, it became Block Five.
 * Phil Collinson chose Hettie MacDonald to direct based on her film Beautiful Thing.
 * The first shot recorded for the episode was the Doctor's hologram, performed on the standing TARDIS set at Upper Boat Studios.
 * Fields House in Newport required little alterations by the production team to serve as Wester Drumlins, although the building's derelict state made the experience uncomfortable at times. Steven Moffat later called the location "the creepiest house" he had ever seen.
 * In adapting his short story, Steven Moffat aged Sally Sparrow up because he figured that children were more interested in watching people older than them. He changed the setting from 1985 to 1969 to make the reveal of the older Billy Shipton more shocking.
 * Carey Mulligan was reportedly ecstatic to have been cast in the series. She was initially concerned with the fact that David Tennant would have little screen time, but after the episode aired was very pleased with the final result.
 * Wester Drumlins was named after a previous residence that Steven Moffat lived in during the late 1990s.
 * Steven Moffat originally wanted to write an episode set in The Library, but his commitment to Jekyll and the realisation that the story would require two episodes led to him shelving the idea.
