John Barrowman has said that he wants to return to Doctor Who when the show celebrates its fiftieth anniversary.
The actor first played Captain Jack Harkness on the long running show, before being given his own spin-off series, Torchwood.
He told Bang Showbiz: "It's the 50th anniversary coming up of Doctor Who and Jack is an integral part to this story and, if I'm going to be a little self-absorbed, I would hope he would be involved, it would be a shame if he wasn't.
"I don't think it's a question of whether I would like to come back as Captain Jack, I'd be very happy to do that any time. I know the fans would really like that. But it's a decision left up to the BBC and the drama department.
"So like I've said to all the fans, you need to write to them if you want it to happen because I've never been asked. I know Russell [T Davies] thinks it might be a nice idea as did [executive producer] Steven Moffat but who knows?"
Doctor Who, which currently stars Matt Smith as the Time Lord, turns 50 in 2013.
