Behind the scenes

 * The space suit costumes worn by Jamie and Zoe in TV: 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 PROSE: Mission: Impractical was an in-joke referencing the fact that Cushing had played the film version of Dr. Who in the 1960s.
 * 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 Doctor Who: The Writer's Tale, the chapter subtitle of which begins "In which George Lucas is snubbed..."
 * A Dalek made a cameo appearance in a (non-canon) Star Wars comic strip, Fett Club. Skaro, Delta Magna and Cygnus are also mentioned in the fan-produced unofficial Star Wars reference guide Book of Imperial Shuttle Plans: Cygnus Spaceworks.
 * 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.
 * David Tennant voiced the droid character Huyang in the Star Wars Clone Wars episodes A Test of Strength and A Necessary Bond.
