Stephen Fry

 voiced the Minister of Chance in the Doctor Who webcast Death Comes to Time.

Fry also wrote the initial script for episode 11 of series 2 of the revived Doctor Who. Believing the episode would be too expensive however, Russell T Davies moved it to the third series so that it could be rewritten. The series 2 slot was filled by Fear Her and ultimately Fry's script was never made as Fry could not find the time to make the necessary alterations. (DWMSE 14)

Outside of the Doctor Who universe, Fry's early acting credits included Fry and Laurie, Blackadder (written by Richard Curtis and starring Rowan Atkinson), and Jeeves and Wooster. He has also been the presenter of the BBC panel show QI since 2003.

Fry has also appeared in a number of feature films, including V for Vendetta, Douglas Adams' The Hitchhiker's Guide to the Galaxy and The Hobbit: The Desolation of Smaug. He was also the narrator of the UK Harry Potter audiobooks, as well as several video games based on the series.

In June 2010, Fry stirred controversy in Who fandom in a speech in which he described programmes such as Doctor Who as "wonderfully written" but "not for adults." Steven Moffat responded by saying the show was "was designed specifically to be a family programme, that's what it's for."

In the DWU
Stephen Fry is mentioned in the novel The Tomorrow Windows as one of the many celebrities attending the opening of the Tomorrow Windows at Tate Modern.

In a throwaway gag in the Christmas special The Husbands of River Song, the Twelfth Doctor incredulously cites Fry as one of the past husbands of River Song. This effectively includes Fry, albeit in passing, as one of the "historical" figures -- like William Shakespeare, Charles Dickens, Cleopatra, Elizabeth I and Vincent Van Gogh -- known to exist within the canonical Doctor Who universe.
