Matt Smith has said that the regeneration fans saw in The Time of the Doctor was very different to other versions he shot.

Speaking at the WonderCon Q&A he said: “It’s very interesting the Christmas episode and particularly the regeneration. We shot so many versions of that.”

He elaborates: “We shot much more brutal, emotional and troubling takes and stories in there. The actual take that is used is an interesting one for me.”

Unfortunately Smith doesn’t go into further details but original reports claimed the 11th Doctor lost a leg at some point.

Smith admits he would have preferred one of the alternative versions: “To be honest, although it’s still a great episode, I think perhaps of what we shot and what was cut I would have chosen differently.”
