Doctor Who's latest guest star is The Royle Family's Ralf Little. Matt Lucas has also been named as another guest to appear in series 10 of the rebooted sci-fi show
The Royle Family star Ralf Little has landed a guest spot on Doctor Who.
Ralf will begin filming opposite Doctor Who actor Peter Capaldi and his new companion Pearl Mackie in Cardiff today.
The actor, 36, who played Antony Royle in the hit sitcom, previously encountered the Doctor when he voiced Guy Fawkes in video game Doctor Who: The Adventure Games.
The BBC said details of his character will be kept under wraps.
Last month, it was confimed that Little Britain co-creator Matt Lucas would return to Doctor Who for series 10.
In the opening episode of the series, he will return as the bumbling Nardole, who viewers met in the Christmas episode, The Husbands Of River Song.
