Ben Whishaw has ruled himself out of the running to play Doctor Who, saying it would be "wrong" to take the role.
The actor, who played gadget master Q in the 24th James Bond film Skyfall, hinted that even if he was offered the part it would be greedy of him to take roles in both franchises.
"It's not going to be me. But I don't mind - I don't think you can be Q and Doctor Who! It would be a bit wrong," he told the Daily Mail.
Speculation about who will portray the 12th incarnation of the Time Lord has been rife since Matt Smith revealed earlier this month that he would be stepping out of the Tardis.
Rory Kinnear, Domhnall Gleeson, Dominic Cooper, Idris Elba and David Harewood are all rumoured to be in the running.
Both Domhnall and Dominic have responded to the reports, with Irish actor Domhnall denying the stories.
"There's nothing to [it]. I heard about it from my agent [who] sent me a website, laughing about the fact that people were saying that I was being talked about. It's not true and there's nothing you can do about people just spouting a whole load of s***e on the internet!" he told RTE Ten.
Dominic admitted he hasn't been approached, adding: "It's nice to be thought about though, wherever it came from."
Luther star Idris said: "I didn't think I'd be very good at Doctor Who. I don't look good in a bow tie..." while Homeland actor David admitted: "It's only rumours but it's amazing to be attached to such an iconic role."
Matt's replacement for the hit BBC sci-fi series is expected to be announced in coming months, with the 30-year-old, who has played the role for three series, tipped to bow out after the Christmas special in December.
