Other mistake: In the scene where Mel Gibson fires off a few rounds into the nearby woods and bushes to see if there are any NVAs, there is a M60 crew, the weird thing about them is that you can only see the muzzle flame from the M60 the first couple of rounds - after that there is no muzzle flame, but the M60 continues to fire at the same rate.
Other mistake: Jeffrey gets pulled over by a cop. He shows his license to the cop and the date of birth is the late 1990s, but he was a young boy in the 70s.
Other mistake: On the DVD, when you put the subtitles on, in the scene where Devon, Jason and Ernest are in their dorm, one of the subtitles say "Jason groans," but Jason is just sitting there doing nothing and it is really Ernest groaning. (00:18:36)
Other mistake: On Caroline's uniform, you see the American flag patch on her right arm (I think it's her right anyway). The flag is backwards. Flag patches worn by military and government officials always has the stars in the front with the stripes following.
Other mistake: Unless there's something I'm missing, Lee, while sitting in that chair peeing, it couldn't possibly go down the side to her left. It'd go down the front.
Other mistake: The 4 kids just snuck into a party. Some jocks begin making fun of Ben, calling him "the chinese Jordan." Daric walking off to check on their puking friend bumps into one of them on purpose. During this sequence, notice that one of the guys is holding a paper cup completely empty just for show, and in the reverse shot it even flips suddenly. (00:37:25)
Other mistake: Eleanor is eating a corn dog with a fork at the ice rink snack bar. Corn dogs are not listed on the menu though.
Other mistake: The "roach" Tim and Francis were to share with the magazine stand man had a length about equal to the width of the man's index finger. The man was able to hold it and take a drag without burning his fingers, but it would have been impossible for Tim and/or Francis to do the same - yet they managed to "get high."
Other mistake: When Richard is at the babysitters he empties an Erector set can but it contains Lincoln Logs. Erector sets came in metal boxes, not cans like Lincoln Logs.
Other mistake: In the scene in the KNX broadcast studio, a shot from the engineer's point-of-view shows VU meters with their needles not moving, even though Bob Crane is talking.
Other mistake: She's holding a Beretta M1951 9mm single action semi-automatic handgun equipped with a suppressor. She takes a shot, and the hammer is full forward. For the gun to fire the hammer has to be all the way to the rear, and after it's fired, the slide would eject the spent cartridge and grab a new one and the hammer would be to the rear. It's not a cowboy revolver where the hammer has to be cocked every time to fire. (00:54:00)
Other mistake: In the scene where Mark Scott is arriving back from being taken into custody by Two River Bend police, the unit's emergency number is a different one, not 9-1-1.
Other mistake: There's no reason for Jane and Will to rendezvous at a small inn given she's got a big hotel suite.
Other mistake: Sy enters the SavMart (after being fired) with a large photo envelope in his hand, and the boss who fired him confronts him about going elsewhere to process his photos, and they get into it. Then Sy pushes past him, and in the next shot, walks right up to the photo counter, when in all previous scenes, the photo lab was at the back of the store.
