Speaking to CultBox on the set of ‘The Day of the Doctor’ in Cardiff earlier this year, the actor explained: “I think what Steven [Moffat]’s done cleverly with an episode like this – which is a celebration, but it isn’t just that – he’s managed to move the narrative of the character forward in a really epic way.”

Smith added: “It makes me really excited to read the Christmas special because I just think ‘God, where’s he taking this?’ I don’t know but it feels it’s climbing this huge slope somewhere.”

He teased: “Hopefully it’s going to be as epic as we can make it.”

‘The Day of the Doctor’ will air at 7.50pm (GMT) on Saturday 23 November on BBC One.
