The Doctor Who biopic - commissioned to celebrate 50 years of the BBC sci-fi drama - will explore the show's 1960s origins.
In a new video clip - running at just under 2 minutes - writer Mark Gatiss acts as a guide on an early morning shoot at London's Westminster Bridge, which recreates scenes from classic 1964 Who serial 'The Dalek Invasion of Earth'.
The original six-part adventure starred actor William Hartnell, who will be played by Harry Potter's David Bradley in the biopic.
Second Doctor actor Patrick Troughton will also feature as a character in the docu-drama, played by Gatiss's League of Gentlemen co-star Reece Shearsmith.
Also cast in the film - directed by Breaking Bad's Terry McDonough - are Brian Cox (BBC head of drama Sydney Newman), Jessica Raine (Doctor Who's first producer Verity Lambert), Jeff Rawle (Doctor Who's associate producer Mervyn Pinfield), Jemma Powell (actress Jacqueline Hill), Claudia Grant (actress Carole Ann Ford) and Waterloo Road's Jamie Glover (actor William Russell).
An Adventure in Space and Time is currently shooting in London and will air on BBC Two later this year.
