Matt Smith and David Tennant make "a tremendous double-act" in the fiftieth anniversary episode of Doctor Who, showrunner Steven Moffat has claimed.
“I wrote it as the friction version,” he tells SFX magazine. “When you’re talking to yourself there are no limitations, there’s no holding back. You wouldn’t be kind or courteous. At the same time, because they are two lovable, madcap, caffeinated Doctors, they’re also quite fanboyish about each other. They think it’s quite cool."
Moffat added that the "funny" dynamic between the two was a "lovely accident" which came about through their onscreen chemistry.
"They’re not broody, upset Doctors – it’s more “There’s two of us! Brilliant!” But that’s mostly in the playing, because they were having such a good time together that they brought that out. They get giggly with each other. It is, by lovely accident, a tremendous double-act.They’re naturally funny together. Enough alike and enough dissimilar. Matt said it was like Laurel and Laurel, as if Hardy didn’t show up – except he does in the form of John Hurt!”
Doctor Who's 50th special, 'The Day of the Doctor', will air on Saturday, November 23 on BBC1.
