In an interview once, Carrie Fischer talked about the scene in Star Wars where they were all running down the corridor. As soon as the first take of the scene was over, she was whisked away so fast they didn't know where she went. When she gor back she told the other actors "They taped me down." Then she talked about auctioning off the right to untape her to the crew after the shoot for charity. Apparently she jiggled too much while running.
