Revealing mistake: As the biker punks roam the streets disturbing shoppers and merchants and endangering people sitting quietly at the cafe tables, the majority of the extras are actually laughing and having a great time even when they are yelling and waving angry fists. (00:14:40)
Revealing mistake: When Moby and Sylvia have the car accident, extras passing by look into the camera a few times, and an elderly couple does not just that, but stops by Sammo Hung. They are not visible in the next shot (and they should be), but appear again later crossing the street on cue from another spot once Lola Forner has reversed the car. In the very last shot, another extra gets in frame for a moment, then has second thoughts (probably realised he missed his cue) and steps back out of frame for no reason. (00:42:40)
