Other mistake: When Ace rescues the dog and replaces it with a toy dog, the toy dog is in an impossible position. Ace had to place it there when the door was still open, but if the door was closed after that the man would have knocked it over. (00:03:25)
Continuity mistake: At the end of the movie when the mob guys come to the boat house to move the body, Barry the Blade shoots a raccoon with his gun which has a silencer. But, later when Reggie shoots the neighbor's alarm system with Barry's gun, it does not sound like it has a silencer anymore.
Suggested correction: The silencer fell off the gun when "the blade" tackled the kid and Reggie. They show the silencer falling off the gun into the leaves.
Visible crew/equipment: When Julie says "It's probably just your nerves" then Heather replies "Nerves?!", above Heather's head you see a boom mic dip down into view. (00:12:25)
Other mistake: When Lamont walks into the alley to avoid being followed by one of Khan's warriors, he makes himself invisible, and his shadow vanishes as well. It's well noted at the beginning of the film that his shadow is always visible even if he isn't. Therefore, his shadow should still be seen on the ground and give him away.
Factual error: Near the end of the film, after Ditch and Krista use the reserve parachute, they fall in a windfarm. The windmills are spinning fairly slowly. After the fight Ditch pulls Pinkwater's parachute out. The wind pulls Pinkwater back towards the fan. Before he gets chopped up there is a shot of the fan blades spinning very fast and powerfully. A light breeze would not cause these blades to spin in this fashion. A hurricane would be needed for those blades to chop up a human.
Revealing mistake: When the killer is up in the radio tower, he tries to force the man up the ladder. He brandished a revolver and you can hear the hammer being cocked back. It shows the revolver more and you can see the hammer is still down.
Visible crew/equipment: When Capa talks to Mrs. Niedelmeyer, there's a 3-foot long shadow of the boom mic on the door.
Continuity mistake: When Cane's agent gets out off the bookstore and crosses the street, the cars keeps changing all the time between shots.
