Other mistake: When the one-legged judge bends over to retrieve his wooden leg from Paul Newman's grandson, you can see the judge's real leg and foot sticking out behind him.
Continuity mistake: In the scene where the grandson is eating ice cream in the Cozy Corner, the ice cream dish is almost full. It then cuts to Sully's face, then back to the grandson and the ice cream dish is empty.
Continuity mistake: Paul Newman steals a snowblower from Bruce Willis. He chains it to a fence. In the next scene Paul Newman is driving his truck through town and the snowblower is still in the back of the pick-up.
Continuity mistake: Paul Newman/Sully had his son jump a fence to steal the snow blower from a construction yard after he drugged the attack dog. PN/Sully then threw him a bolt cutter to break the chain that locked the blower. I doubt he carried a self propelling snow blower over the fence - he must have come through a main entrance. So why not cut the lock on the fence to begin with?
