Behind the Dolphin Smile chronicles Richard O’Barry’s extraordinary journey from dolphin trainer to world-renowned advocate for dolphin freedom. In his early years, O’Barry trained dolphins to entertain audiences for shows at aquatic theme parks and for roles in movies and television shows, most notably Flipper. His career as a trainer came to an abrupt halt when one of the dolphins that played Flipper on television died of stress in his arms. At that moment, he realized that keeping dolphins in captivity and teaching them to do tricks was cruel and morally wrong. He began to understand that dolphins were easy to train not because of his gifts as a trainer, but because they are remarkably intelligent, and he vowed not to rest until he freed every last one of them.
