During an A&E Biography, Michelle Pfeiffer said that her Catwoman costume was vacuum sealed once she was fitted into it for scenes, so she actually had only a short amount of time to perform before she would have to have it opened or she could become light headed and pass out. She also admitted that when she was first learning to use the whip she accidentally cut her trainer’s face with it, at which he acted as a complete gentleman and continued with their training.
