Star Wars

Star Wars was a science fantasy saga of movies and other "expanded univese" material.


 * At the end of a holographic message to Jack Harkness, renegade Time Agent John Hart mockingly said "Help me, Obi-Wan Kenobi, you're my only hope", a line from A New Hope. (TW: Kiss Kiss, Bang Bang)

Behind the Scenes

 * The duel on the Sycorax asteroid in The Christmas Invasion appears to be a reference to the duel between Darth Vader and Luke Skywalker in The Empire Strikes Back, such to when the Doctor lost his hand and sword off the edge of the asteroid, mirroring Luke losing his hand and lightsaber to Vader.


 * Later in the episode, the destruction of the Sycorax asteroid by the Jathaa weaponry is similar to the Death Star's destruction of Alderaan in A New Hope.
