Little Britain star David Walliams is starring in a new BBC film by writer and director Stephen Poliakoff.
He features alongside Maggie Smith and Jane Eyre actress Ruth Wilson in Capturing Mary, which will also be shown in the United States.
The TV funnyman, 35, plays a “subtly evil man” who feigns friendship but brings about destruction instead.
Smith, 71, plays Mary, a once-brilliant writer and critic who is reflecting on her younger self and is haunted by the memory of Walliams’ character Greville.
The BBC2 film will be shown beside another interlinked Poliakoff title for BBC1, which has the working title Poliakoff 2006 and stars Michael Gambon.
Both dramas are being shot in central London later this year and are set in the same grand, empty house frozen in time.
The narratives in the two films are told through the eyes of teenager Joe, played by newcomer Danny Lee Wynter, son of the cleaner of the house.
The films are also being made for US network HBO.
Since shooting to huge success with Little Britain, Walliams’ other film credits have included A Cock And Bull Story and Virgin Territory, featuring Hayden Christensen and Mischa Barton, which is currently in production.
Controller of BBC Fiction Jane Tranter said: “It takes a major piece of work and a unique auteur to deliver a project that straddles two BBC channels.
“Stephen Poliakoff is such a talent and with the depth and breadth of the amazingly gifted cast assembled across Poliakoff 2006 and Capturing Mary, I am certain that the finished product will be awe-inspiring.”
