After learning that Sam is indeed Ben and the 'waiting period' is over, when the family finally goes to pick him up and bring him home, you'll notice that Michelle Pheiffer (sp) is wearing a black skirt and beige sweater/blouse and that her hair is pulled back. Then during the scene when the whole family sits down for dinner and Sam asks for a glass of milk ('You do milk with pizza?') her character gets up and seems to have changed into a mauve sweatshirt and lavender sweats and her hair is down. The very next scene is when the parents go into Sam's room to say good night...and she is wearing the skirt and blouse again and her hair is pulled back once more.
