Marion Cotillard, in a black and white Alaia dress, and her Rust and Bone costar Matthias Schoenaerts attended a luncheon for their project at Brasserie Ruhlmann in NYC yesterday. It's already been a big week for Marion, who attended the Gotham Independent Film Awards in a Christian Dior dress on Monday night. She, along with Matt Damon, was honored with a Tribute award for her work in film. Marion's latest movie opened in limited release last week, and press duties have been keeping her in the spotlight. She's featured on the cover of W magazine's December issue and also recently participated in The Hollywood Reporter's actress roundtable.
