Doctor Who star Karen Gillan has promised sidekick Amy Pond will make an appearance in the Christmas special.
In the last series Amy was seen getting married and becoming a mother and Karen has been away in New York filming We'll Take Manhattan, about the love affair between Jean Shrimpton and David Bailey.
But she revealed: "Amy is in the Christmas special, with her husband Rory. It's a cameo appearance but we're in there.
"It was really fun, I think we were only down for one evening, just came on set and ran around on set like we always do, it was like we never left. It was great fun."
The 23-year-old actress, who joined the BBC science fiction series starring Matt Smith as the Doctor in 2010, said she will miss playing Amy when the time comes to leave the show.
She said: "I think I will miss it, it's like no other job. It's too much fun and I'm sure that I will never do a job like it. So I'm just really savouring it and the time will come when Amy has to go, I don't know when that is yet though."
