Olivia Munn, a prominent actress and action film star, has revealed that one of her former male co-stars, refused to let her character save his during a scene during filming. The incident occurred during a bunker fight sequence where both characters were defending their positions before switching sides. Munn said that the script called for her unnamed co-star to be nearly shot from behind until her character stepped in. The actor immediately halted filming and argued with the director in front of the entire crew. Despite this, Munn still got the role. She has previously spoken about other difficult experiences on set, including losing out on a role on "30 Rock" due to Alec Baldwin thinking she was too young to play.
