Other mistake: When the Predator sees Billy on the log bridge, there is a cold blotch in the middle of Billy's chest. He's not wearing anything that would make such a hole in his heat signature - it should be the same color as the rest of his torso. It doesn't even match up with the cut he made across his chest; the cut starts much higher than the blotch and the blotch is irregularly shaped, not indicating the smooth line of a cut. (01:15:20)
Suggested correction: The cold area is the blood running from his wound. It is cooling down on contract with the air.
Continuity mistake: When Mac is killed by the Predator we see a shot of the Predator fully cloaked standing over the camera. As he slowly moves off to pursue Dillon there is a brief shot of Mac's twitching body with an un-cloaked object rising through the branches above. (01:08:55)
Continuity mistake: During the montage scene of the remaining men setting the net trap for the Predator, all of the men are each doing individual jobs. Dillon does not take part initially, until Arnold says 'Instead of complaining, maybe you should help.' However, long before Arnold tells Dillon to help, Dillon can actually be seen helping out already. Watch closely...when Mac throws a rope across to Billy, Dillon is standing behind Mac, with his shirt off, fastening a rope to a tree, as if he was helping the whole time already. A similar shot occurs after Arnold's comment, but the first one is definitely before. (01:02:05)
Continuity mistake: When Dutch is running from the Predator after he sets the grenade off in the tunnel sequence, he avoids the Predator's gun blast by leaping and swinging on the branch of a dead tree. As Dutch's flying through the air, you can clearly see that it is a real branch. But as the screen switches to an explosion and back to Dutch, the branch is now some prop 2x4 and collapses as Dutch now plunges into the pond below. (01:33:20)
Revealing mistake: When Dillon and Anna are arguing in the terrorists hideout near the burnt out helicopter, the corpse on the ground behind them moves his foot.
Revealing mistake: While the Predator is healing himself with his surgical material, the marks of the brands are visible.
Revealing mistake: While Dutch is struggling with the Predator in the jungle, in several shots the stuntman is visible.
Other mistake: The time of the chopper arrival for rescue (after the village attack) is said to be 09:30 but the voice on the radio says 10:30.
Suggested correction: Maybe the pick-up time changed. When Dillon (Red Fox) calls Blazer One for extraction (after the village fight and Blane's death), he's told "next contact 9:30." Dillon confirms pick-up at 10:30 hours.
Continuity mistake: In the last helicopter scene the General's rank changes from 1 star on his hat to 2 stars on his collar.
Visible crew/equipment: When Mac and Dillon are hiding in the hole talking about how they are going to kill the predator, a boom mic is briefly visible at the top of the screen between them. (01:10:20)
Continuity mistake: Early in the movie, Mac throws the dead green berets' dog tags to Dutch. As he catches them, Dutch has his hand closed in a fist, and the dog tags are hanging to the left. But in the close-up shot where we can read the name, his fingers are more open, with the tags resting in his palm.
Revealing mistake: Blaine is dead in the body bag, but when Mac puts the flask on his neck, you see his pulse.
Plot hole: After Blaine gets killed and the group hose down the forest, Poncho goes and checks for the enemy. He comes back and says he didn't find tracks or blood "We hit NOTHINGGG." Now, while he would be looking for red blood, he certainly should have noticed at least the glowing Predator blood (made from glow stick fluid - widely used by the military and public alike at the time) easily visible on the large leaf, and deduced that came from something - perhaps the enemy soldier had a glow stick.
Suggested correction: This isn't a plot hole. The plot of the movie isn't broken because of this. It's an assumption that he "should have noticed" the predator blood but he might not have. And if he had, and had discounted it, it would only be a character error not to have mentioned it.
A plot hole doesn't strictly need to "break" the plot to count as a plot hole. The term most often refers to instances when a film contradicts its own sense of internal logic. For example, something happening that contradicts something else that was already established, vital information being left out, or a character acting way out of character for the benefit of the plot. In this case, this absolutely could count as a plot hole.
Other mistake: During the assault on the guerrilla base we see Mac running through the brush towards the camera firing his gun without aiming. It then switches shot to behind him, and he is turning towards a pair of men to shoot them. Plus the way he was moving and firing his gun isn't consistent with a professional soldier and their gun discipline and why would he be shooting randomly before engaging? (00:25:30)
Continuity mistake: In the chopper, as Arnold asks about the backup, you can see Poncho sitting on the other side of Dillon. It's not until later in the scene where Poncho moves from his seat and sits next to Dillon for the remainder of the scene.
Other mistake: Right at the end, Arnold fires an arrow at the Predator which barely takes flight and fires very slowly. He is shown making the bow very tight so the arrow should come out very quickly.
Character mistake: When Mac describes what he saw after Blaine was killed, he states that he "capped off 200 rounds with the minigun." At the rate the minigun fires, and the length of time Mac was shooting, he fired at least 10 times that amount. Perhaps he meant to say "capped off 2000 rounds." This adds to another mistake: the ammo pack Blaine carried only holds 500 rounds but much more than that is fired during the course of the film.
Suggested correction: He actually says "capped off 20 rounds, in the minigun...full pack" just the word spacing is a bit odd. 20 rounds refers to his normal gun which ran out of ammo quickly.
No, he says "capped off 200 rounds." I've just watched it with subtitles on. What I heard (200) matched with the subs.
Continuity mistake: While the team are hearing the music on the chopper, the pushed buttons on the recorder change - the third one, then the fourth, then none.
Continuity mistake: Before the team finds the crashed chopper Dutch has just a bit of camouflage on his face but after that he has more.
Continuity mistake: At the beginning while Dutch meets with Dillon the cigar in his hands disappears and reappears between shots.
