Keira Knightley has revealed that she is enjoying filming her new movie Anna Karenina and is excited to be juggling all the ideas about her character.
The movie sees her reunite with director Joe Wright, with whom she worked on Pride and Prejudice and Atonement, for an adaptation of the Leo Tolstoy.
And the actress admits that she saw different sides of Tolstoy's writing and the character when she has returned to the novel as an older reader.
Speaking to Interview magazine the actress said: "It's very exciting. We're right in the middle of it. It's totally different than this; it's a very, very stylised version of it, and she's a tricky character.
"I remember reading it as a teenager and just seeing the romance of it. Then all of a sudden I read it over the summer, and thought, 'Wow. Sometimes Tolstoy actually hates her quite a lot. Is she the heroine or the anti-heroine?'
"It's an interesting thing, with all of us, we're sort of grappling with those ideas. You don't want to simplify anything, because it should be an exploration of somebody who breaks their own moral code, and what happens when you break your own moral code. It's really interesting, and fingers crossed it will work."
Knightley leads an all star cast in Anna Karenina that includes Jude Law, Matthew Macfadyen, Aaron Johnson and Kelly Macdonald.
But before we see her in Anna Karenina the actress will team up with Steve Carell for Seeking a Friend for the End of the World, which is directed by Lorene Scafaria.
Anna Karenina is released 7th September.
