 During an A&E Biography, Michelle Pfeiffer (qv) 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 first was  learning to use the whip she accidentally cut her trainers face  with it, at which he acted as a complete gentleman and continued  with their training.
