Accounts differ on just how many actors and behind-the-scenes workers suffered injuries on “Roar." Hedren says it was a mere seven; others, including one of her sons, claims it was 72. No one disputes the worst of the incidents, including cinematographer Jan de Bont getting scalped by a lioness and requiring more than 200 stitches. (He went on to direct “Speed” and “Twister,” but “Roar” remains the most nerve-wracking thriller he ever made.) Hedren got bucked off an elephant and fractured her leg, not to mention multiple scalp wounds from run-ins with her big-cat costars.
