The 27-year-old was happy to get naked and expose a lot of skin with Jake, 29, in the movie.
Anne told MTV News: 'I don't think there's anything wrong with nudity in film, and I would hope that any actor that is asked to reveal that part of themselves has as loving and open an experience as we had.'
She added: '[Jake and I] talked about it and we talked with Ed [director Edward Zwick] about it and we said, 'You know, we're gonna do what we feel comfortable, let's talk about why we feel this is important, let's talk about the story we hope to tell through these scenes.'
'I think there's a big difference between having nudity and having two characters living their lives without their clothes on.'
