In 1599, the first Back to the Future film was mentioned by the Tenth Doctor to help explain the mechanics of time travel to companion Martha Jones. Martha didn't see any threat from the Carrionites because she knew that the world didn't end in 1599. However, the Tenth Doctor referenced this movie when he told her about how Marty McFly, after he travelled back in time, did something that almost erased him from existence in the present.

When Cristián Alvarez contacted the Seventh Doctor by leaving a letter with UNIT to be passed on to him, Bernice Summerfield noted that it was just like in Back to the Future. (PROSE: The Left-Handed Hummingbird)
While the Eleventh Doctor was explaining his plan to return Mark Whitaker to 2011, he told Mark that he was here "to take you back... to the future!" He then added that he had "always wanted to say that." (PROSE: Touched by an Angel)
In the 25th century, Stewart Ransom became a fan of Western films, particularly Back to the Future Part III, which influenced his decision to establish the technological limits of the Independent Earth Colony on Axista Four to the Western period as part of his dedication to the "Back to Basics" program. The Second Doctor claimed that the second film in the trilogy, Back to the Future Part II, was better. (PROSE: The Colony of Lies)
Behind the scenes Edit
Possible allusions Edit
- In Blink, there was an allusion to Back to the Future Part II, as someone was told to give a letter to Sally Sparrow at a specific date and time, no earlier, no later. This relates to how Doc Brown sent Marty a letter at the conclusion of Back to the Future Part II.
- Peri Brown and Erimem use the same method to get letters to the Fifth Doctor in The Kingmaker. Peri notes that she got the idea from a film. If she is referring to Back to the Future Part II, she must have seen the film during her travels with the Doctor as it was not released until five years after her native time.
- The TARDIS drawing room has numerous clocks similar to the garage of Emmett Brown at the beginning of Back to the Future. (GAME: TARDIS)
- The Scorpion King mentions that the Doctor's TARDIS has a flux capacitor. (AUDIO: The Boy That Time Forgot)
- In Face the Raven, there is a poster on a wall in the trap street which displays something closely resembling a flux capacitor. There is writing next to it in Aurebesh, the alphabet prominently used in the Star Wars franchise, which spells out "Delorean" - the model of car central to the plot of Back to the Future.
- In Back to the Future: Part III, Doc Brown breaks his own rules of interfering with fixed points in time, to save the life of the woman who would become his best friend and love, the schoolteacher Clara Clayton. This storyline is in many respects similar to the Twelfth Doctor's rescue of Clara Oswald. (TV: Hell Bent)
Invalid sources Edit
The website whoisdoctorwho.co.uk had a list of sightings of the Doctor which people had ostensibly been submitting to Clive Finch, a conspiracy theorist character from Rose. In actuality, the submissions were from visitors to the website; one such submission, credited to "Marty McFly", simply reads: "I know that man, he stole my DeLorean!!!" 
The 2015 cross over game Lego Dimensions included Doc Brown and Marty McFly as playable characters in a Back to the Future Lego world. In advertisements for the game, shots of Doctor Who and Back to the Future elements intertwined were highly emphasised.
Other matters Edit
- The trilogy provided the name for the band McFly, which had a cameo in The Sound of Drums.
- In 2012, Karen Gillan professed her love for Back to the Future Part II and her desire for a hoverboard.
