Other mistake: In the final gun battle when the Regulators are trapped in the attic of the burning house, one of the characters backs into the brick chimney that's coming up through the floor. You can see the entire chimney move when he backs into it.
Other mistake: When the bad guys are stealing the drugs and they use the spray to break the lock, they drag the chain off the bars, and if you look closely you can see part of the bar chip off and it's made of wood. (00:08:10)
Other mistake: Pay attention to one of the early innings of the baseball game as one of the Angels players hits a home run. Though probaby intentionally set up this way as to avoid any problems of "logo patents" and such with the real life MLB California Angels team, he is wearing a helmet without the team logo on it. (01:07:35)
Other mistake: When Bryan is replaying the conversation between him and Kim, as she was being kidnapped, you can hear parts of the conversation that happened before he started recording.
Other mistake: In one shot, during the lynching, the noose comes undone from the character's neck while he is hanging.
Other mistake: When Gavilan is leaving the building after his first interview with Sartain, he passes a memorial wreath with pictures of H20Klick's members. The banner reads "In Memorium" which is a misspelling. It should read "In Memoriam".
Other mistake: Throughout the movie, Fred MacMurray wears his wedding band, even though it's mentioned several times that he is single.
Other mistake: In the beginning the detective is a detective but during the exciting hunt for the killer (when Diane Lane's character is abducted), the detective is referred to as a Lieutenant by his people over the radio.
Other mistake: Throughout the movie we see the mustang rolling chassis in the garage. This is a rolling chassis of a 1967 Shelby mustang gt 500/350. The main ways to realize this are that the car has the cut outs in the front for the 2 fog lights that the Shelby had and that the back end has a spoiler which is built into the body. However the car they do all the driving with is a base model 1967 mustang fastback. While a new grille would've covered up the fog-light cutout, the regular fastbacks didn't have the built into the body spoiler like the Shelby's did. Removing the built in spoiler and making it as smooth as it was would've taken way too much time and supplies. It also wouldn't have served any benefit. You could argue they were trying to eliminate down-force on the back but the spoiler was only about 2 inches, it wouldn't have helped. The directors did this to avoid wrecking the much more rare Shelby mustang.
Other mistake: A police helicopter nearly crashes and has to veer away because of the superheated air around the building when only a few floors are on fire, but Will Sawyer and everyone else can function normally when half the building is ablaze. In fact, everyone barely breaks a sweat despite being surrounded by flames.
Other mistake: Will did not have enough time to place into the pot at the poker game. For those at the end of a hand, they each have contributed a minimum of an equal percent based on the number of people in the hand. There were potentially 5 people at the start of the hand, and Will did not have enough to cover 20% of the final pot. He would have needed well over 200 years available, and we know he had a little over 100.
Other mistake: When Big Boys' men drive through the garage door trying to escape, Dick Tracy, the cops and the goons start opening fire. Yet, nobody seems to feel the need to stop and reload their weapon. They just keep firing without ever running out of bullets.
Other mistake: During the restaurant shoot out between Jr and the bad guys, he takes Sasha's weapon (Kel-Tec P-3AT) and opens fire on the bad guys. The Kel-Tec P-3AT is chambered in .380 and holds 6+1 rounds. During the firefight, Jr fires 9 times. We also see the bottom of a spent casing and it shows .22. (01:12:00 - 01:13:00)
Other mistake: The date on the surveillance footage from the camera in the Russian Embassy says 01.05.08, implying that it is either January or May (depending on which date notation is being used, American mm.dd.yy or Russian dd.mm.yy). However, it is fall/autumn outside, as there are dead leaves everywhere. And when Katie calls Harry we can see that his cell phone shows 17/9/08. (00:48:00)
Other mistake: Crews is talking to his wife by telephone and says he is in North Carolina. The signage shows he is at the I-85/I-26 interchange in Spartanburg, South Carolina.
Other mistake: In the opening scene where the two cars race. they use a traffic signal to start the race. This traffic signal is in the middle of nowhere and there is no intersection at this light and a single lane road. Also, there aren't even supports for the traffic light on either side (which would be necessary because the light is suspended from a wire), which is most visible during the crane shots.
Other mistake: Toward the end of the film, Cora and Frank put the top up on their roadster, then drive off without latching the top.
Other mistake: Towards the end of the scene in which Vince Vaughn and Jon Favreau are arguing in front of the penguin exhibit, as Vince Vaughn gets rolling with his speech the movement of his lips fails to jibe with the soundtrack.
Other mistake: When T. jumps through the rear window of Nick's van he falls on the street but rolls the wrong way, against any laws of physics. (01:21:05)
Other mistake: When Tommy and Archie are in the tank keeping the arms dealers distracted, Tommy turns his head to see what the noise he heard is(Vanessa breaking out of the van), allowing the laser technician to get behind a dual .50cal machine gun. However, it takes about 25 seconds for the laser technician to get to the gun and for Tommy to look at him. Tommy should have only glanced at the noise, but instead he looks and stares at it for a long time - 25 seconds. He would have easily seen and heard the technician going for the .50cal and had 25 seconds to pull the trigger and kill him. (01:22:00)
