Keira Knightley enjoyed being the centre of attention at the premiere of her latest movie in London last night (31.01.12).

The British actress - who looked stunning in a floorlength Burberry dress with Louboutin heels - laughed and joked with her 'A Dangerous Method' co-stars Michael Fassbender and Viggo Mortensen although she admitted she was uncomfortable with some the spanking scenes in the film.

She said: "I was in doubt about doing it because of two specific scenes in the film that are of a masochistic nature and I actually phoned up the director David Cronenberg and said, 'Look, I love you, I love your work and I love The Script, but I don't know if I want to do this.'

"He said, 'OK, we'll take them out.' But in that medium, you can't not see what you are talking about. So anyway, we talked about it and we talked about it. So the fact that he didn't want to make it sexy or voyeuristic but kind of brutal and strangely clinical, I sort of went, 'OK, let's do it.'"

While Keira was uncomfortable with some of the scenes she appeared to be enjoying herself at the afterparty at 34 Restaurant in Mayfair where she danced with co-star Michael before sharing a kiss with her boyfriend, The Klaxons frontman James Righton in the car as they left.
