Continuity mistake: When Cher is held up by the guy with the gun after the Valley party, he tells her to get down on the ground. Take a look at her necklace - it's a small silver heart on a silver chain. She gets down on the ground, counts to 100 and gets up again. Check out the necklace now - it's still the silver chain, but the pendant on it is one of those nameplates that says 'Cher'.
