John Barrowman has hinted that he may return to Doctor Who for David Tennant's final episodes.
The actor has starred as Captain Jack Harkness on several occasions during Christopher Eccleston and Tennant's time as The Doctor and has since appeared as a lead character in spinoff Torchwood.
When asked about a return for this year's Doctor Who specials, Barrowman told Metro: "I'll put it this way - Captain Jack will always return to the side of The Doctor when he needs assistance."
Regarding the popularity of his character, he added: "I think it's the fact I'm portraying somebody people can identify with. Whether it's because he's omni-sexual or he's proud of who he is - he doesn't give a s**t about what anybody thinks.
"If I had a formula, I would sell it! I'd be handing it out on street corners for ÂĢ1.50 each. I have been absolutely overwhelmed by the popularity and success of Captain Jack."
