Matt Smith reveals details about the Doctor Who Comic Relief special

Matt Smith has revealed some details of the upcoming Doctor Who Comic Relief special.
The actor will appear in two four minute episodes for the charity event, alongside Karen Gillan (Amy Pond) and Arthur Darvill (Rory Williams).
“It’s great,” Smith told TV & Satellite Week. “The set-up is that the three of us are all in the Tardis together, and the Tardis materialises within itself and there are two Amy Ponds. It’s a real jaunt and a bit of fun.”

When asked for more details on how two Amy’s will come to be in existence, Smith added:

“I couldn’t possibly say, but she is quite pleased to meet herself, put it that way. Rory is bemused by the whole affair but, needless to say, two Amy Ponds in his life is no bad thing.
“Karen really enjoyed playing two versions of herself and it is a really funny performance from her. We are always laughing during filming anyway, but it was really nice to get to do a sitcom-like story in the Tardis.”
He added: “Sometimes it is good to do something out of context and stand-alone and not have a full story narrative to follow.”
