Continuity mistake: What top Dr. Casey Brackett is wearing (or not) in the decontamination chamber changes. Initially, she removes an off-white short-sleeved T-shirt-like top before putting on the protective gown. When she returns to the chamber, an automated voice says to "remove outer garment", which she does - but she is now wearing a sleeveless off-white top that was not under the gown. When she ducks down to hide from the Predator, she does not have ANY top on. (There may two+ different short-sleeved tops). (00:22:33 - 00:31:28)
Continuity mistake: After the small predator kills everyone in the back of the truck he grabs a left arm that becomes a right arm. (00:37:25)
Revealing mistake: The covering of snow was not real snow. When the trick-or-treaters are first seen, there are images of footprints (shoeprints) in the snow, but the trick-or-treaters walking over the "snow" do not leave any footprints. (00:44:38)
Continuity mistake: The little boy, Rory, gets to a baseball field after his mask blows a hole in some guy's chest. On the field the bulldog comes up to him and then the Predator dog shows up. Rory is standing there and has the Predator's gauntlet on his left arm, but in the shot where he and the bulldog look up at the other Predator dog, suddenly the gauntlet is on his right arm and his left arm is up and empty, only for it to jump back to his left arm for the rest of the scene. (00:51:26)
Other mistake: It isn't known if Rory was diagnosed with ASD, but some of his behaviors and the two classmates in school making a reference to his "Asperger's" indicate or suggest this is the case. While Rory may have been "faking" some mannerisms in hope that the two bullies would leave him alone, his (hyper) sensitivity to noise (sound) was displayed after school when a dog was barking at Rory. However, Rory did not put his hands over his ears in the ball field despite the loud gunshots close to his ears. (00:51:54)
Other mistake: At the baseball field after Quinn (Rory's dad) slid through the green slime, he only had green slime under his neck on the front of his shirt - none on his pants or back of shirt where expected. (00:52:52 - 00:53:37)
Plot hole: As the evolved Predator's ship takes off it leaves Casey Bracket alone in hilly forest terrain. The ship then flies a long distance before crashing and the Predator and McKenna start fighting, just for Bracket to show up and help out of nowhere. Impossible for her to cover that distance that fast in hilly forest terrain.
Plot hole: Quinn gave the box containing the Predator's equipment to a Mexican and told him to send it to a P.O. Box in the U.S. He also gave the man an unknown amount of money for the postage. Without questioning IF the Mexican would follow his instructions and had enough money, sending a package internationally is not that simple. The package would need to go through customs and several documents would need to be completed. The contents must be disclosed. It is doubtful it would pass Customs.
Continuity mistake: When Rory holds the predator's mask from the box it changes position between shots.
Continuity mistake: After the small predator wakes up at the lab he holds a woman as a shield using his right arm then the left then the right again.
Continuity mistake: When Casey tries to leave Quinn and the others at the motel he throws her her bag but a second earlier it was already on the bed.
Continuity mistake: After Casey and the others get to the lab Casey has her purse on her left, then on her right.
Continuity mistake: After Rory leaves the helmet on the ground the marks on it change sides.
Continuity mistake: After Mckenna holds the small sphere in his hand, a bag appears beside him that was not there before.
Continuity mistake: After Treager leaves the chopper at night, he is holding the box of gum in his right hand and the candy in his left but in the next shot he has the gum in his right.
Continuity mistake: While the predator is about to crash it's still daylight but as he lands it's dark already.
Continuity mistake: After the predator crashes, McKenna jumps and falls with his machine gun on his left, then it disappears, then is on his right.
Suggested correction: I agree this APPEARS to be correct, but I think it is questionable - it COULD be the left arm. The covered thumbs-up arm the Predator extended to the driver had its fingers curled toward the palm, not straight out like they were. There was a zigzag pattern on the glove's wrist, but this could be the opposite (outer) side if it also had the pattern, not the inner side. The thumb looked broken - giving the image that it might have been the right thumb, but actually the left. You MIGHT be right.

The mistake is valid, no correction needed. It's a right hand that extends through the opening and a left arm seen on the floor. A key factor is the knuckles location, so it doesn't matter if the thumb looked broken.

I watched several times and still believe it could be the left hand. The way the fingers are folded (curled) toward the palm, they look like left knuckles.
KeyZOid
If the hand was a left hand, then you wouldn't see the knuckles.
Bishop73
No matter which way fingers are folded under toward the palm, there will be knuckles showing on either side. (Make a fist and see for yourself!) No further replies from me here.
KeyZOid
Then you misunderstand what I mean by knuckles. I'm talking about the metacarpophalangeal joint, not the interphalangeal joint.
Bishop73
No, I didn't... and knuckles are knuckles! [Now, no additional replies from me here.].
