Well, it’s official. Not only is Bernard Cribbins appearing in one of the final David Tennant stories, but on-set photos also show John Simm has returned to Doctor Who! The image at right (credit for the photo goes to alun.vega) shows Cribbins and Simm passing each other on-set.
Cribbins played Donna’s grandfather Wilf Mott in series 4, and of course John Simm appeared in series 3 as The Master. So far, this substantially confirms recent rumors that Tennant’s final stories would feature a return of Martha Jones, Donna Noble, Rose Tyler (again!), Wilf Mott, and the Master.
