Star Wars

Star Wars was a popular science fiction film series from Earth which was made in the 1970s and the 2000s, comprising a total of nine films by the 2040s. (PROSE: The Last Resort) Iris Wildthyme was cast in the third film as a woman in a gold bikini and was the only woman in the film with lines other than Carrie Fisher as Princess Leia. According to Fisher, Iris was fun to be around but difficult behind the camera, due to her demands that she use her own wardrobe and make-up and her inability to recall her lines. Iris claimed she could convey everything with just a look, but they eventually had to recast, to her displeasure. (PROSE: Drowned in Moonlight)

The Sixth Doctor and Frobisher attended the American premiere of the first film at Mann's Chinese Theatre in May 1977. Frobisher appreciated the original film and was aware of its place in culture, but the Doctor claimed to prefer the Special Editions. He also thought the actor who played Tarkin looked familiar, and seemed to remember meeting his granddaughter. (PROSE: Mission: Impractical)

Behind the scenes

 * Fitz's reference to Star Wars films being made in the 1970s and 2000s roughly pertains to the original trilogy and the prequel trilogy respectively, though in reality the last installment of the original trilogy was produced in the early 1980s while the first of the prequel trilogy was produced in the early 1990s. This reference, made in the 2003 novel The Last Resort, predates the real world production of the sequel trilogy which took place in the 2010s, but does correctly predict that a series of nine Star Wars films will have been released by the 2040s.
 * The Doctor's recognition of Peter Cushing in Mission: Impractical was an in-joke referencing the fact that Cushing had played the film version of Dr. Who in the 1960s.
 * The Day of the Doctor novelisation mentions Peter Cushing appearing in movies after his death as a reference to his CGI recreation in Rogue One.
 * In A Confusion of Angels, Bill Potts, upon hearing the name of the starship Jeden, coins the phrase "Return of the Jeden", to which Nardole adds "The Last Jeden", a reference to the 1983 film Return of the Jedi and the then upcoming 2017 film The Last Jedi.
 * Steven Moffat has been nicknamed "the Moff" and "the Grand Moff" by fans as well as by Russell T Davies after he took over as executive producer for Doctor Who in 2010. "Moff"/"Grand Moff" is a high military rank in the Star Wars universe.
 * Russell T Davies received an offer from George Lucas to write a story for his television spinoff series Star Wars: The Clone Wars but Davies turned it down for lack of time as well as a lack of desire to write for a sci-fi franchise he didn't build. The occasion was discussed by Davies in Chapter 4 of The Writer's Tale, the chapter subtitle of which begins "In which George Lucas is snubbed..."
 * A Dalek made a cameo appearance in the Star Wars comic strip Fett Club. Skaro, Delta Magna and Cygnus are also mentioned in the fan-produced unofficial Star Wars reference guide .
 * Darth Vader appeared in a Top Gear sketch where he was pitted against other opponents including a Dalek, a Cyberman and Colin Baker as the Sixth Doctor to see who the fastest "Master of the Universe" was around the Top Gear track. Vader was seen helping the Cyberman put its helmet on, and he was later exterminated when the Dalek became angry that it couldn't fit in the car.
 * On a poster in the Trap Street in Face the Raven, the Star Wars alphabet of Aurebesh is used to spell out "Delorean", which is itself a reference to Back to the Future, another popular Sci-Fi film series.
 * Robert Harvey, the sound designer and composer for Across the Darkened City, compared the Chaons from that story to Rathtars from The Force Awakens. (BFX: Across the Darkened City)
 * Sam Kent-Smith was an artist on the video game Star Wars Battlefront: Renegade Squadron.

Props

 * The space suit costumes worn by Jamie and Zoe in The Wheel in Space was later re-used in the original trilogy (most noticeably by Bossk the Bounty Hunter). Similar costumes (which were re-purposed High-Altitude Windak Pressure Suits that had been used by the RAF during the 1960s) had previously appeared in The Tenth Planet.
 * Behind the Magic showed an "early blaster prototype" reusing one of the ballistic weapons of the Daleks from Death to the Daleks. The muffle was later reused for Ponda Baba's custom DL-21 blaster pistol prop which itself was reused for soldiers in Empire Strikes Back.
 * The antique prop picked up by Romana I from an altar in episode 2 of The Power of Kroll was reused for the Gaderffii.

Star Wars happened
In the BBC New Series Adventures novel Forever Autumn, the Tenth Doctor states that Jar Jar Binks and his clan are good people, that George Lucas received telepathic messages and mistook them for his own ideas, and that he would be "way off the mark" by Episode 9, implying that some (if not all) of Star Wars is real. Although Lucas did not end up making the film, there was an Episode IX made and released into theaters in 2019, validating the Doctor's claims.

In Supremacy of the Cybermen the Ninth Doctor claims the TARDIS made the Kessel Run.

Though it may be coincidental, the Star Wars: The Clone Wars episode "" has the Father mention the Laws of Time.

Blaster weapons and skimmers exist in both universes.
