Factual error: When Brad does the jump shot to make the 8-ball, we can see the cue ball as it leaves the rail, and there is no way that it could result in the position on the nine ball, in the next frame.
Factual error: At the end of his first session with the lady doctor, the serial killer touches a guard and makes him crazy. The guard goes into an office, grabs a shotgun, sticks it right under his chin and pulls the trigger. The gun is pointed straight up, but the blood splatters straight back onto the wall behind him, not up into the air.
Factual error: The Point & Shoot Camera Sy uses throughout the movie (Minolta Freedom Zoom 150) has a lit in-viewfinder readout. The real camera does not have any fancy readout, just a thin circle to help center and frame your image.
Factual error: At the end of the movie, Harry Truman is quoted in 1954 in laying out the domino theory, but it was his successor, Dwight D. Eisenhower who did that.
Factual error: Al Pacino is the subject of an internal affairs inquiry in Los Angeles. It's unlikely a police officer under investigation in L.A. would be sent to Alaska to work on a murder case. Police officers under investigation are routinely given desk assignments until officially cleared and allowed to return to active duty.
Factual error: To start his first mission, Frank has an alarm set on his watch. The watch he is wearing is an Officine Panerai. This brand makes only mechanical watches. But what is heard going off is an alarm on a quartz watch. (The only Panerai with a mechanical alarm looks completely different.)
Factual error: This movie takes place in Philadelphia (or Pittsburg?) but was filmed in Montreal, Canada, and they had to do a little thing to hide this. In a pursuit scene, you can see a street panel with Montreal's logo written Rue St-Jacques. In another scene, the building that is supposed to be a bank is in reality a library and the name is still on it.
Factual error: When the Dalmatian and her new puppies are shown, the puppies are standing and their eyes are open. However, a new born puppy's eyes are sealed shut until they are at least 12 days old and they can only crawl on their bellies. (00:05:19)
Factual error: When the kid is trying to get the girl to come into his car, he is listening to Number of the Beast by Iron Maiden, and the editing is terrible. It jumps from the middle of the recital from the book of Revelations at the beginning to the opening guitar riff and then far to early into the famous lengthly scream by Bruce Dickinson. (00:52:00)
Factual error: No way the sound of Jenny's voice calling for Malloy from afar through Slater's walkie-talkie was this loud and with no noise at all (at Malloy's end) from the storm she and Slater was in.
Factual error: A two minute free fall from a helicopter? Not unless the helicopter was flying at 230,000 feet, which is more than 5 times the record altitude achieved by one.
Factual error: In the paramilitary roadblock scene, you can see the license plates of several vehicles, and these plates are not Colombian. In all other scenes, the overall appearence of the license plates match actual Colombian ones.
Factual error: John supposedly goes to Chicago to talk to a mothman expert, but it shows the two of them walking into The Mellon Institute which is actually in Pittsburgh.
Factual error: In the scene where, Clint is examining his scar, the scar is misplaced. It should run from the top of the sternum between the collar bones to the bottom of sternum, mid diaphragm.
