Twice Upon a Time (Doctor Who) and Time". This makes him the third actor to play the role in the television programme, after William Hartnell and Richard Hurndall (in 1983's "The Five Doctors") since the premiere of "Doctor Who" in 1963. Bradley previously played Solomon in the 2012 episode "Dinosaurs on a Spaceship". The first trailer for the episode was shown during the 2017 San Diego Comic-Con, revealing the return of Polly, a companion from the end of William Hartnell's tenure as the First Doctor, portrayed by Lily Travers, and Pearl Mackie as Bill Potts.

Peter Brachacki were obviously the same sets as were used for the Doctor's TARDIS, slightly redressed. The TARDIS interior was completely redesigned again for the 1996 "Doctor Who" TV movie, and the new series that began broadcasting in 2005. Even then the central console was retained, and the new television series includes the geometric patterns on the walls. In 2013 the BBC produced a docudrama called "An Adventure in Space and Time", depicting the creation and early days of "Doctor Who", as part of the programme's fiftieth anniversary celebrations. Brachacki appears as a character in the drama, played by actor David Annen.
