According to NiceMatin.com

, in which she plays an orca trainer who loses both legs in an accident during a show.
Cotillard appeared calm and focused as she stood inches away from the massive mammals and put fish into one gaping (and very toothy!) mouth. She's clearly learning how to stay safe around these creatures!
