Hostility on the Set: Penelope Ann Miller apparently acted like a diva and the crew disliked working with her. Peter Kent, Arnold Schwarzenegger's stunt double, decided to get back at her by giving Arnie, unbeknownst to the actor, pasta with tomato sauce made with juiced vegetables on a day when he knew Arnie and Miller would be shooting in an enclosed space. Miller had no choice but to endure Arnie's uncontrollable farting and, as an unintended consequence, Arnie had to deal with the discomfort of trying and failing to hold it all in.
