Kathy Bates, Dan Akroyd, Rupert Everett, Jonathon Pryce, Julie Andrews, Barry Manilow, etc. Kind of a bizarre movie, but Kathy Bates is a joy to watch. I've loved her ever since seeing Misery. (I went with a friend, who was pretty freaked out by the movie, and later, it was so fun to call his house and leave messages for him from Annie Wilkes.) She is really a great actress. She sings in this movie, too, and her voice is great. All of the acting in this movie was very good, actually.
Not necessarily recommended viewing, but it was entertaining.
