Star Wars

Star Wars was a popular science fiction film series.

Behind the scenes

 * The space suit costumes worn by Jamie and Zoe in DW: The Wheel in Space was later re-used in the original trilogy (most noticeably by Bossk the Bounty Hunter).
 * The Doctor's recognition of Peter Cushing in PDA: Mission: Impractical was an in-joke referencing the fact that Cushing had played the film version of Dr. Who in the 1960s.
 * Dave Prowse, who had a small role in DW: The Time Monster played the body (though not the voice) of Darth Vader in the first three films.
 * The duel on the Sycorax asteroid in DW: The Christmas Invasion may take some cues the duel between Darth Vader and Luke Skywalker in The Empire Strikes Back. In both scenes, the hero (the Tenth Doctor in this case) loses a hand and the weapon held in it. Later, the destruction of the Sycorax asteroid by the Jathaa weaponry is similar to the Death Star's destruction of Alderaan in A New Hope. The Valiant had similar weaponry in DW: The Poison Sky.
 * The Face of Boe's final words to the Doctor: "You are not alone" are similar to Yoda's final words to Luke Skywalker: "There is another Skywalker".
 * In Last of the Time Lords, the Doctor tries to redeem the Master rather than kill him. This is similar to Luke Skywalker trying to redeem Darth Vader rather than kill him.
 * The funeral pyre scene in Last of the Time Lords is very similar to the funeral pyre scene in Star Wars Episode VI: Return of the Jedi.
 * The villain Davros is very similar to Emperor Palpatine/Darth Sidious (though, since Davros' first appearance predates Emperor Palpatine's by almost a decade, the resemblance is at least unintentional, at most from the opposite direction). They are both evil galactic emperors with hideously scarred wrinkly faces who can attack people by firing lightning from their fingertips. They also have similar voices.
 * The Dalek Crucible is similar to the Death Star.
 * Star Wars creator George Lucas is an avid fan of the original Doctor Who series.
 * Actor Harrison Ford (Han Solo) was offered the role of the Eighth Doctor in the 1996 Doctor Who television movie but turned it down rather than have a television commitment tie him down. (At the time, the movie's producers hoped to make it the pilot for a re-launched Doctor Who series.)
 * In The End of Time, the Master turns good and sacrifices himself to save the Doctor. That scene is like the scene in Star Wars Episode VI: Return of the Jedi when Darth Vader turns good and sacrifices himself to save Luke Skywalker.
 * The alien bar scene in The End of Time is very similar to the Mos Eisley Cantina scene in Star Wars Episode IV: A New Hope.
 * The reference in NSA: Forever Autumn to Jar Jar Binks he is in fact a part of the Doctor Who universe, and not just a reference from a film.
 * The fight scene between the Spitfires and the Dalek Saucer in DW: Victory of the Daleks is remenisent of The Battle of Yavin from Star Wars Episode IV: A New Hope
