Star Wars

Star Wars was a popular science fiction film series from Earth.

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

 * 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 alter in episode 2 of The Power of Kroll was reused for the Gaderffii.
 * 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 novelization mentions Peter Cushing appearing in movies after his death as a reference to his CGI recreation in Rogue One.
 * Star Wars villain Darth Vader was played by Minotaur actor Dave Prowse, while the voice of the Star Wars villain Darth Maul was provided by Fisher King voice actor Peter Serafinowicz.
 * The Star Wars character General Ackbar was played by puppeteer Tim Rose, who went on to operate the Cybermats in Closing Time, and to design the animatronics for the Half-Face Man in Deep Breath.
 * 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.
 * Carolyn Seymour voiced various characters in a number of Star Wars video games.
 * David Tennant voiced the droid character Huyang in the Star Wars: The Clone Wars episodes "A Test of Strength" and "A Necessary Bond" — and became the only vocal performer to win Emmy for their work on that show.
 * 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.
 * Tom Baker voiced the Force-wielding character Bendu in season 3 of Star Wars Rebels.
 * Felicity Jones played the lead character in the 2016 film Rogue One.
 * 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)
 * Miles Richardson played governor Diles Anevi in the 2018 film Solo.
 * Tosin Cole played Bastian in Star Wars: The Force Awakens.
 * Sam Kent-Smith was an artist on the video game Star Wars Battlefront: Renegade Squadron.

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 will not be making it, it has since actually been confirmed that there would be an Episode IX of Star Wars.

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 exist in both universes.
