Steven Moffat has revealed that Matt Smith and David Tennant loved working together so much in The Day of the Doctor, that the pair would have liked to have done more episodes together.

He told the Radio Times: “They got on like a couple of old women. They just say in the corner and gossiped the entire time. By the end of it, Matt told me that he’d worked out this plan that they’d both continue in Doctor Who: do five individual episodes each and three together – would that be ok? It was a nice plan. I think if I’d said yes they’d have gone for it.”

Moffat added: “The double act between them is sublime. It’s one of those happy accidents – there’s no reason why they should be, but they are absolutely adorable and hilarious together.”

“David and Matt, I think… were both quite apprehensive of the other. David’s continued to watch Doctor Who like the sad old fan he is and so as far as he’s concerned Matt’s the Doctor. And of course for Matt, you don’t believe yourself you’re the Doctor, you just think David’s the Doctor. So they were both slightly nervous and slightly apprehensive.”
