Other mistake: In the slaughterhouse scene, after Harrigan has injured the Predator with his shotgun and Keyes reappears, the Predator throws its disc, and severs Keyes in half at the waist. We see his legs flop to the ground, and blood pour from above, but his upper half (torso, backpack and weaponry) mysteriously remain hovering out of sight. (According to the director, the MPAA made him cut the footage of the top half of his body hitting the ground because it was too gory, creating this odd error). (01:21:50)
Other mistake: At the carnival, you can see an African-American man staring at the camera for a while. I am unsure if he is a crew-member watching over the scene, or if he is just an extra trying to get onscreen.
Other mistake: In the music within the ending credits, the lyrics incorrectly state that Raph is the leader of the group when all Turtle fans past and present know it is Leo.
Other mistake: When Marty returns to 1985 from 1885 the time machine is destroyed by a train. What is strange is that not only does the train not stop (which is mandatory in the event of an accident) but there is also no reaction from people nearby, such as those in the vehicles waiting to cross the track at the level crossing. Later, when Marty returns to the site with Jennifer, there is still no sign of police officers or other officials.
Other mistake: In the scene after Arnold kills the construction hoods he goes home to Sharon Stone and tries to convince her that it was real by showing her his bloody hands with which he was grabbing her shoulders, yet there is no blood on her or the appliances he turned off upon entering the apartment.
Other mistake: Irv and Blaire's death scene doesn't make sense. When Irv poured butter on the popcorn, he should've noticed the spider in the bowl. Also, when Blaire picked the spider up, she should've felt it. Both of them still appeared to be watching the TV after being bitten, which also didn't make sense. Why didn't they have seizures like the other victims?
Other mistake: When the President escapes from his cell, he immediately calls down to Sharon. Not only does he not know Sharon, no-one has given him any indication she's even down there, and she's also not said anything to raise awareness of her being there, or her name.
Other mistake: Gizmo can't be exposed to sunlight, yet when the shop is demolished he walks out on the street. Note how he is walking past the shady part of the curb to the sunny part, suffering no harm whatsoever.
Other mistake: Once Earl stops the CAT at Burt and Heather's house, Val is standing on its roof directly above Earl. Val is looking and talking straight at them. The graboids shake the CAT, Earl drives it forward quite a bit (take notice just how far), but he looks up to tell Burt to hurry but he and Val are still facing in the same direction. They should be facing backward due to the distance they had to move up. Also, you'll notice that Burt is right in line with the trailer as he throws most of his gear. (01:14:30 - 01:15:30)
Suggested correction: We don't actually know if the disc completely cuts Keyes in half (or just passes through him and leaves a gaping hole). You see the blood, but the movie is edited so that it cuts back to Harrigan looking on in horror for a split-second, then back to Keyes' body on the floor (mostly obscured by a cement pillar).
They blatantly show his legs hitting the ground without the top half! I can only assume you watched an edited-for-TV version or something. It's VERY clear in the movie that he was cut in half. (In actuality, the scene was the victim of the MPAA according to the director... they had to cut the bit where the top half of his body hit the ground because it was too gory... creating this odd movie mistake).
