Jean Seberg only had one line in the first scene shot, which she shared with Peter Sellers and Leo McKern. For the first several takes, she stepped forward for her line, then back when she was finished. When Arnold pointed this out to her, she said she didn't even know she was doing it. By the time she got her movements under control, she couldn't remember the line. After 25 takes, Arnold postponed the scene until a few days later.
