Keira Knightley has said working with Sir Kenneth Branagh on Jack Ryan: Shadow Recruit felt very "schizophrenic" as he flitted between Russian villain and polite British director.
The British actress was joined on the red carpet in London's Leicester Square by co-star Chris Pine and director Sir Kenneth, who also stars as Russian villain Viktor Cherevin.
Keira laughed: "It was hysterical. The main reason I did this film was for Ken Branagh - I've been a huge fan of his since I was a kid and the opportunity to work with him, not only as an actor but as a director, was something I couldn't say no to.
"So it was totally mad, because he's playing the nastiest villain you can imagine, who does some horrific things to me. So he'd be completely horrendous, and screaming in my ear and all the rest of it, and then suddenly go, 'Okay ladies and gentlemen, thank you so much. And that's a cut and that was lovely', and be this sweet man. So it was quite schizophrenic."
The action thriller, based on the novels by Tom Clancy, sees Pine take on the role of the CIA agent previously portrayed on screen by Alec Baldwin, Harrison Ford and Ben Affleck.
Pine donned a tweed suit and dapper silk pocket handkerchief for the premiere, and revealed he'd regretted not visiting a tailor on Savile Row while filming the movie in London.
He confessed: "I was desperate to get a suit made, which I failed to do, but it's still on my bucket list. And I wanted to get pair of shoes made but I did buy a page boy hat.
"I love British style, the tweed is definitely my ode to the British banker of the 30s."
Jack Ryan: Shadow Recruit, which also stars Kevin Costner, is released in cinemas on Friday .
