Bruce Forsyth (in-universe)

Sir Bruce Forsyth was an accomplished British actor and television presenter during the 20th, 21st and the 22nd centuries.

Biography
Bruce was a well known celebrity by at least the 1960s. (AUDIO: The Final Act)

Forsyth's life and career continued right across the 21st century and into the start of the 22nd. The Eleventh Doctor accidentally brought Dermot O'Leary to the year 2111, where O'Leary was amazed to find Forsyth still alive and working at the BBC while not looking any older. (TV: Dermot and the Doctor)

Behind the scenes

 * Dermot and the Doctor's claim that Forsyth was still alive and working by 2111 is a reference to the star's longevity. Of course, inevitably, Forsyth passed away in 2017. Forsyth's life in the 22nd century has never been contradicted in any other source.
