Catherine Tate is bringing her character Nan to the big screen in This Nan’s Life.

Mathew Horne is reprising his role as Nan’s grandson and the cast will also include Katherine Parkinson.

The film will explore the origins of the profanity-laden pensioner Joannie Taylor, played by Tate.

The film has been co-written by Tate and will be directed by Josie Rourke, who made Mary Queen of Scots.
