Daniel Craig had to get in bed with Rooney Mara "pretty much straight away" after they met on the set of 'The Girl With the Dragon Tattoo'.

The actress admitted things moved fast on the set of the film, and she found herself practicing sex scenes with her co-star during their first meeting.

She said: "I met him for the first time at a screen test. We had to get into bed together pretty much straight away."

Rooney plays the gothic styled computer genius Lisbeth Salander in the film, and while she her look is striking in the film, she believes it is more about context than her dyed hair and piercings.

She added to OK! magazine: "I think the character, in her setting in Stockholm, is quite shocking because it's quite reserved there. If you put the character in New York's East Village, people wouldn't really look twice at her.

"It definitely changed people's reactions toward me - they didn't pay as much attention to me and maybe their expectations were lowered, but there wasn't that big of a reaction."
