Marion Cotillard premiered Rust and Bone Saturday night at the BFI London Film Festival in a little black Dior dress. Keeping her company on the red carpet was her leading man Matthias Schoenaerts and their director Jacques Audiard. Marion kept the public appearances coming yesterday, too, stepping out in a printed Azzaro frock for a Q&A session at the BFI Southbank Centre. We caught up with Marion back in May at the Cannes Film Festival to learn about the film, in which she plays a woman who overcomes a great deal after losing both legs in an accident. Marion thinks she's like her Rust and Bone character, and told us, "I definitely have strength . . . it would be a long conversation on how strength is manifested in yourself, but there's very few things that — actually, I don't think there's one thing I could think about that could put me down."
