Continuity mistake: The last shot, when the camera pans away from the front door of the house, appears to be taken from a helicopter, and a modern 1990's white car can be seen parked behind the property in a courtyard.

Continuity mistake: Rocks destroys Daphne's house, and attempts to make it up to her by fixing her broken food bowl. He pushes the two pieces together with his nose, and they are not flush. In the next shot, he puts his head up and you can see that it's a full bowl without any cracks.
Continuity mistake: During the final fight between Jean-Claude and the bad guy, they are both holding onto a shotgun. Initially the barrel of the gun is in J-C's left hand. But without either of them letting go of the gun, suddenly the gun switches end-for-end and the stock of the gun is in J-C's left hand. It looks like they probably re-filmed the last of the fight so the bad guy could use his right hand to hit J-C with the butt-end of the gun.
