Gemma Arterton has a new movie out, Hansel and Gretel. Not exactly for the kids. But neither are Rule 5 posts.
She has been in other movies too, she was a Bond girl in Quantum of Solace, she was Io in Clash of the Titans, and Princess Tamina in Prince of Persia. As a matter of trivia, she is also polydactyly (born with extra fingers).
