Continuity mistake: When Ali leaves the club with Marcus the first time she is wearing a grey dress with a large keyhole opening in the back. When she gets back to Jack's apartment the next morning she is wearing a grey dress with no keyhole in back. Instead the grey dress has a straight-across back with spaghetti straps. Oops! Wardrobe goof.123qwerty
Continuity mistake: In the scene where Cher practices her solo, "You haven't seen the last of me" she starts to sing sitting on a chair facing the camera. As the camera angle changes her hands are exposed differently or in a different place on the chair. While singing, she stands and she moves the chair to the side. In subsequent angles, the chair is in different positions behind her, shown laying on its side, disappears, and when she finally walks off the chair is nowhere in sight.
