“The absolute reality was we didn’t have all those Doctors about to come back through the door. There were limitations to who we could get back.They’re all brilliant, they’re all terrific, but time has passed. I think it would be beyond the dignity of all those very fine actors to want to force themselves back into a costume from 20 or 30 years ago.”
“I was thinking more “What would be a grand old story for the Doctor? And what would speak to the generation who are watching it now, while still celebrating the fact that it’s been around for all that time?” Everyone wanted to see David (Tennant) again – that’s just a fact. And David and Matt together are glorious. That’s a joy.”The classic Doctors will unite in a two-hour audio adventure from Big Finish, The Light at the End, later this year.
