Within minutes of her arrival for the first day of rehearsal at the Marineland in Antibes, in the South of France, Marion Cotillard was required to watch the whales perform for a crowd. "I was jet-lagged and sensitive," she recalls. A female trainer assigned to work with her on her character asked what she thought. "I didn't want to be disrespectful, but I said, 'I'm sorry, but I have to be honest - I hate this situation. I hate to see animals doing clown things. I think it's horrible', she remembered.
