Actor Bernard Cribbins will return to Doctor Who as the Doctor’s companion, in David Tennant’s final two episodes on BBC One this Christmas.

Bernard has previously starred as the grandfather of Donna Noble (Catherine Tate), at the end of the fourth series in 2008.

“It’s one of the greatest delights of my career to welcome Bernard Cribbins back on set, this time as a fully fledged companion to the Doctor,” executive producer Russell T Davies told Doctor Who Magazine.

“And if Wilf’s back, then the Noble family aren’t far behind! David Tennant’s finale also sees the return of Catherine Tate as Donna Noble because there are a lot more twists and turns with Donna’s story.”

Russell assured the public that Catherine Tate has promised to keep her schedule clear for her return to the show.

“You might be wondering how Donna can return, since her mind is supposed to burn up if she ever remembers anything about her life with the Doctor?” teases Russell.

“Sorry, but you’ll have to wait until Christmas to find out!”
