Steven Moffat has insisted that Peter Capaldi’s Doctor is “not at all elderly in style.”
Speaking at the official Doctor Who 50th Celebration at ExCel London, Moffat said that Capaldi “leaps around the place” in “post-regeneration madness”.
"We’ve only seen the tiniest moment - it’s just the beginning of a process. But of course, he’s brilliant and he’s an extraordinarily vital and physical performer."
Moffat insisted that Capaldi is “not at all elderly in style.”
"People keep talking about this ‘elderly’ Doctor that we’ve cast… he leaps around the place probably more than any other Doctor in that first scene," Moffat revealed.
"But that’s not how he’s going to play it - that’s just him in the post-regeneration madness. It’s something we’re still working on."
Speaking about the Christmas episode itself, Moffat revealed: “It is a proper finale to Matt Smith. It’s the story that we’ve been telling since he first put the bow tie on - that’s what we’re going to resolve.”
"A lot of stuff we’ve left hanging we tie up there. And it’s Trenzalore!"
Doctor Who Christmas Special 2013 will air on Christmas Day (25 December) on BBC One.
