Torchwood star John Barrowman is not holding out much hope that the hit sci-fi series will return any time soon.
The Doctor Who spin-off, created by Swansea's Russell T Davies, ran to four series, the most recent in 2011.
Barrowman, who plays Captain Jack Harkness, said: "It's in limbo, in a sense.
"Something could be done in five years, something could be done in 10 years. But if I'd sat around and waited for the last two years I would have been bankrupt and unemployed, so I've moved on."
Barrowman can currently be seen in Sky One's comic book adventure Arrow.
