Keira Knightley bows out of the race to play Ana Steele

Despite rumours that Ryan Gosling will be playing Christian Grey, recently engaged Keira Knightley isn't at all tempted to star with him in the movie of 50 Shades Of Grey.

Keira had been hotly-tipped as a favourite for the racy role of Ana Steele but the 27-year-old is adamant she doesn't want a part in the sexy flick.

'Absolutely not! Just from what I've heard - f*ck no,' exclaims Keira.

'The hardest thing to capture about love is the actual physical intimacy between two people. The way two people behave when they are next to each other and touching each other.

'That's a difficult thing to capture on film.'

After spending months working on stressful and emotional scenes for Anna Karenina, the Brit actress is enjoying the chance to work on more light-hearted projects and doesn't intend to attempt another intense role for a while.

'I wanted to do something happy and positive and just have a bit of a break from that,' says Keira

'I went off to New York, I did an incredibly happy and positive film about friends who make an album.'
