Former Doctor Who companion Catherine Tate does not foresee a return for her character Donna Noble in the future.
Unfortunately I think Donna’s storyline would prevent her from coming back, because any memory of the Doctor, of her time travelling with him, and the adventures she embarked on, would kill her. So I can’t see a storyline being able to bring her back.
She did however reveal that she is very keen to reunite with former Doctor Who co-star David Tennant, following post-Who appearances together on stage in Much Ado About Nothing as well as Tate’s television sketch show:
Yes, working with David is the best. We get on so well and it’s just always so much fun. I don’t know how to describe it – it’s just that something clicked when we first started working together from day one on The Runaway Bride and hopefully will continue to. We’re looking for future projects together.
I think Peter is wonderful in the role, and I’m really enjoying the 8th season. He’s a fantastic actor, and his wit and intelligence shines.
