Sir David Jason says his desire to know what happened to one of his most famous characters inspired the return of 70s sitcom Open All Hours.
He is reprising his role of Granville in a one off special of the show this Christmas.
Sir David was talking to BBC Breakfast about that return and another new project, his autobiography.
