An Adventure in Space and Time is a 2013 British biographical television film, starring David Bradley, Brian Cox, Jessica Raine and Sacha Dhawan. Directed by Terry McDonough, and written by regular Doctor Who writer Mark Gatiss, it premiered on BBC Two on 21 November 2013, to coincide with the 50th anniversary of the science fiction television series. Further, international broadcasts of the television film were made after its premiere on British television.

The biographical film focuses on a dramatised version of events surrounding the creation of Doctor Who in the 1960s, with emphasis on actor William Hartnell, portrayed by Bradley, as he took on the role of the original incarnation of the show's main character, the Doctor. Alongside Hartnell, the story also focused on the behind-the-scene events with the production staff, including the involvement of Sydney Newman, Verity Lambert and Waris Hussein. The television film received positive feedback after its broadcast and received a number of award nominations. Following his role in the film, Bradley would take part in Doctor Who in the role of the First Doctor, for the 2017 episodes "The Doctor Falls" and "Twice Upon a Time", and the 2022 special "The Power of the Doctor", as well as for a series of audio adventures for Big Finish Productions.
