Great film, but...
1. The cop takes his gun out of the holster and sets it down. Does it not have a safety or what? He just leaves it sitting there, even when someone runs into the place and is obviously distraught. You'd think a trained police officer wouldn't leave his weapon in just any old public place.
2. The plot was just confusing. Why did Allen's character screw over Terry? Why did Terry need to enter the competition at all? If his wife was in on some set-up, then why would she need the money from the winnings to settle her $30,000 debt? Why did Allen make Terry a co-producer of a Hollywood film and just bail on him the next day?
3. Why would a police officer take a $20,000 watch to a pawn shop? You take gold watches to a jewelry store or auction it off over a computer or something. A dirty pawn shop that sells 25 cent SNES games won't be able to pay you off for that.
A lot of the mistakes or slip-ups are important plot points and had the filmmakers spent a little more time thinking about it, it would've made it better.
