Marion Cotillard touched down at JFK today, pushing her baby boy Marcel Canet along in his stroller as they headed to a waiting vehicle. Once Marion got her little guy settled in the backseat, she helped keep him happy by entertaining him with some of his toys. The mother and son often travel together, and when they're not jetting around, have been spending the bulk of their time in France. She's been busy shooting her latest film, Rust and Bone, in and around Antibes. Marion even went topless during a recent day on the set of the movie, in which she stars a killer-whale trainer. The role is the latest for Marion following her part in the upcoming Dark Knight Rises. She got to work on the action-heavy film just a few short months after welcoming Marcel to the world in May, and was spotted with costars including Christian Bale and Tom Hardy working on a battle scene in Pittsburgh over the Summer.
