Marion Cotillard Topless Pictures on Rust and Bone Set

Marion Cotillard took off her t-shirt on the set of Rust and Bone in France today. She went topless to film a scene in the water with her costar Matthias Schoenaerts after the duo prepped on the beach. Marion arrived in the South of France last week and she brought her son, Marcel, along to the location. The 4-month-old stayed behind for a recent day of prep in Antibes, though, where Marion practiced her killer-whale training skills at Marineland. Her son has been traveling with her since his birth in May, and they've stopped in LA and NYC as well as in Marion's hometown of Paris.
