Story notes

 * This is the first story to feature Rose in the capacity of the Doctor's companion since Doomsday.
 * Lucius Petrus Dextrus from The Fires of Pompeii says that "she is returning" when seeing the future. This is most likely a reference to Rose's return in this episode.
 * Billie Piper was seen at the end of Partners in Crime, as well as a short cameo in The Poison Sky.
 * Chipo Chung was last seen in the episode Utopia as the Malmooth, Chantho. She plays a human character in this story.
 * This is the 'Doctor-lite' episode of the series, similar to Love and Monsters and Blink.
 * A reference to something on Donna's back was last heard in The Fires of Pompeii when Lucius Petrus Dextrus saw into the future 'something on your back' is a back story arc as it has never been mentioned up to this episode.
 * In DWM it is said that Donna will recieve a free tarot card reading and find out something bad is going to happen. When she is recieving it their will also be something behind her lurking in the curtains. The Tarot person will also look for a specific event in Donna's past.
 * Part of this episode is filmed in China Town though not the one in London, China Town was recreated in Cardiff. Chinese people living in South Wales were invited to be extras via Facebook at the end of 2007. They had to reply to the Doctor Who casting crew with their name and sizes for costumes to be made for them and, they were paid approx £70 for a day. David Tennant was seen in 'China Town' when he took time out of filming but stayed on location to appear on Blue Peter to appeal to viewers to donate shoes to their Shoebiz appeal.

Rumours

 * Enemies likely to be in this episode include Davros and Dalek Caan. Davros was seen in the trailer but in darkness. Several Daleks also appeared but whether Dalek Caan was there is unknown. The trailer also expresses a scene containing four (imperial?) daleks.
 * In the previous episode descriptions it claimed rose's world is 'splintering'. Maybe Davros/Daleks forcing their way in is causing reality to splinter.
 * In a trailer seen on BBC One, Donna's granddad looks up to the sky and sees the stars "going out" possibly something to do with the Void. (or perhaps maybe the Vashta Nerada).
 * Harriet Jones will appear in either this episode or the next, with her uneasy alliance with The Doctor after The Christmas Invasion, she may be working or influenced by the Daleks, alternatively it may be the Harriet Jones from the parallel world.
 * Davros will be shot and/or killed in the final episode, either by Harriet Jones (revenge) or by Rose, to stop him destroying earth.
 * We see flashbacks of Donna before the events of the runaway bride.
 * Other Rumoured titles for Episode 12 are Ruins of Skaro, Ruins of Gallifrey, The Medusa Cascade, Children of Time, The Oncoming Storm and War on Skaro.
 * Possibly takes place during the events of the Time War, "The Time War" being another likely title.
 * The reason Rose, Jackie and Mickey returns is because Pete's World collapses sending anything not from that universe back to their original universe.
 * Davros causes Pete's World to collapse by attempting to punch a hole in the fabric of space time in order to reach the Daleks trapped in the void.
 * Pete's World collapses, and Rose manages to find a path through the Doctor's World, not realising that she has opened the void. This allows Davros through, as he was trapped in the void after the Time War. Rose rectifies this at the end of the series.Likely, as Pete (in Doomsday) stated that his world was at the brink of "flooding", due to void disturbance (Daleks and Davros?).
 * A plausible reason as to why this episode is titled "Turn Left" may be due to the fact that Rose is on the right side of the void and the Doctor is on the left. Point being: for Rose to "Turn left" into the "real" world. (Based on scenes in Doomsday)
 * Confirmed by a T.V magazine, Davros will return as the main villain of the story.

Continuity

 * In The Sontaran Strategem the Sat Nav kept saying Turn Left. The Doctor is also heard saying Turn Right not Left. This could have something to do with this episode.
 * Rose says in the mid series trailer that the darkness is coming, the Toclafane say "Its coming ... the never ending darkness". (DW: The Sound of Drums) This was most likely a reference to heat-death of the universe, a main topic of Utopia (TV story). Gwyneth also mentions "the darkness" in her Rift-induced prophecy (DW: The Unquiet Dead).
 * In the Fires of Pompeii it is mentioned that Donna has 'something on her back'. This is a device sent by Davros to help him gain control of Donna, thus gaining control over the actions of the Doctor.

DVD and Other releases

 * This is due to be released in the Series 4 boxset in November 2008 along with the rest of the Series.
 * It will be released as Series 4 Volume 4 alongside Episode 12 and Journey's End in September 2008.
