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 on Friday.
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.
Matt Lucas was last month confirmed as another Doctor Who guest star for series 10.
In the opening episode of the series, he will return as the bumbling Nardole, who viewers met in Christmas episode The Husbands Of River Song.
