Peter Capaldi will be "amazing" in his Doctor Who role, one of his latest co-stars, Jason Flemyng, has predicted.
Jason stars opposite Peter in BBC One's swashbuckling drama The Musketeers, in which the former plays notorious criminal Vadim with the latter as Cardinal Richelieu.
"He will smash it. He's going to be amazing. He's so talented," he said.
The 47-year-old said his co-star will be an "amazing" replacement for Matt Smith, who has left his role as the Time Lord in BBC sci-fi series. Peter is expected to make his debut as the 12th incarnation of the Doctor in the coming series.
"The Doctor is a great role. They've never had a bad Doctor," Jason continued.
"In the modern Doctor Who, they've never cast an OK actor. Every single time, the actor's been sublime and talented, and that, plus the fact it's a good role, has turned Doctor Who into a great character.
"You can't just play the Doctor. It doesn't work unless you have a great actor and Capaldi is the best. He's one of the best."
He added: "One minute I was working with Peter playing the Cardinal and the next, I was working with Doctor Who. That was quite surprising when he got the Doctor Who gig while we were in the middle of it. When I did The Quartermass Experiment, David Tennant came in one morning and was Doctor Who as well so it seems to be something strange, like I'm a lucky (charm). Always the bridesmaid, never the bride."
Jason, whose father Gordon directed both of the Dalek feature films of the 60s - Dr Who And The Daleks in 1965, and Daleks - Invasion Earth: 2150 AD - admitted he has little interest in portraying the Doctor himself.
"Until they stop the Daleks flying and put them back in the spaceship, which is where they're meant to land, then I shall be keeping away from Doctor Who," he said.
"(That's) the most ridiculous thing I've ever heard. Much as I love the show, suddenly the Daleks start flying and I thought, that's silly."
Having starred in films such as X-Men: First Class, The Curious Case Of Benjamin Button and Kick-Ass, Jason will return to the small screen as notorious criminal Vadim in The Musketeers, playing the villain to the four swashbucklers - D'Artagnan (Luke Pasqualino), Athos (Tom Burke), Porthos (Howard Charles) and Aramis (Santiago Cabrera).
He will make his appearance in the second episode of the show, which will be shown at 9pm on BBC One on January 26.
" Vadim is a proper old-school Saturday morning film club baddie. It was great," he said. "I took a little bit of all the great baddies of all time - there's a bit of Errol Flynn in there when he's really bad, there's a bit of Lee J Cobb, a bit of (Humphrey) Bogart.
"I don't really do too much telly so it was great to do. It's really fun, and the boys are fantastic. I'm meant to be Luke's enemy and I didn't know whether to stab him or kiss him."
