EW also have a short interview with Steven Moffat in which he discusses the team-up between the two Doctors:
“We’ve authentically re-created the First Doctor. We could put it out in black-and-white, and you would think it was William Hartnell. There’s new monsters, there’s new jeopardy. But what’s fascinating is the First Doctor confronting the superhero he’s going to become, with his supersize TARDIS and all that.”
The Comic Con panel will take place next Sunday at 10.30pm UK time, and it will supposedly see an ‘exclusive preview’ of the Christmas Special.
