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: Just after Austin recollects what Mini Me did last time he used the peace symbol, they both smash bottles to use for fighting. Austin grabs his out of a gift basket and Mini Me grabs his out of the mini fridge. Considering the location of both Austin and Mini Me's bottles, shouldn't liquid come out of the bottles because they are new? (01:03:40)
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 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.
