The actress previewed her first appearance as Clara in Doctor Who's Christmas special in a new featurette released by the BBC, where she suggested that the series is like nothing else on television.
"It's just so much fun," Coleman said of Doctor Who. "There's no other show or no other job where you can do some of the things that you get to do... It really is a one of a kind show!"
Coleman went on to offer hints about her own plans for Christmas Day, when BBC One in the UK and BBC America in the US will broadcast 'The Snowmen'.
"On Christmas Day, I will be in a cottage in York with family, curled up on a couch watching [Doctor Who]," she said.
She then teased: "It's not at all nervewracking - not at all! I'll probably be scrunched in a ball watching [with my hands over my eyes]."
Coleman recently said that she doesn't feel like a replacement for Karen Gillan and Arthur Darvill, who exited Doctor Who in 'The Angels Take Manhattan' after two and a half series as The Doctor's companions.
"It's a whole new story, it's a whole new character," she stressed. "It changes the Doctor and you've got to go on that journey and also go on your own journey with it, as well."
'The Snowmen' airs at 5.15pm on BBC One in the UK and at 8pm on BBC America.
