Goofs

When Dutch is being pursued by the Predator and is sliding down the hill that leads to the cliffs, there is a rocky and dry riverbank extending at least 50 or more feet from the cliff base, to include a tree between where Dutch would land and the river. In the next shot, Dutch falls into to a deep body of water with no riverbank at the cliff's base.

Throughout the film the team use items such as a grappling hook and Claymore mines. Yet they are very visibly never carrying these items in scenes where they are not required.

During the terrorist camp attack, a man with a mustache, red bandanna on his neck and a hat is seen shooting down at Mac, who promptly hides behind some rock and tells Blain to help and kill him for him. Blain fires ahead and the man is then seen being shot dead, falling down and smashing through a roof next Hawkins and Poncho. Next, some more terrorists are seen to pop up to start shooting, one of them being the same man with the mustache, red bandanna around the neck and a hat who was seen being killed just seconds earlier.

Right after Dutch gives the plan for attacking the rebel camp, Blain and Mac walk off screen to the left. Blain is carrying the mini-gun ready to use it. In the next shot the mini-gun is shouldered and his M16 is being carried.

After Dutch swims to shore, he crawls through the mud, turning to see the Predator coming towards him. Dutch reaches for his Rambo like knife only to find it missing. Yet, after the Predator is out of sight, Dutch is using the missing knife to improvise weapons and his defensive position for the final confrontation.

At the end of the movie the predator initializes a self destruct sequence. As Dutch runs away to save his own life, the background is lit up from the explosion. None of the trees or their leaves actually move from the force of the explosion.

At 3 minutes, the blades of the helicopter (high pitch whooshing sound) are noisier than the rotor and engine, which is technically incorrect.

In the scene when Billy is taking a stand and ready to face the predator he rips of his fatigues and then slashes himself across each chest and blood immediately oozes as he's cuts himself blood does not immediately ooze out of a cut wound until at least 8 seconds after being opened..

When Dutch's team is setting up the trap for the Predator, Poncho drops some jungle "rope" onto the camera and tells the cameraman to "look out."

In the shot right before this, Anna is holding the jungle "rope" at the bottom of that same tree. The jungle rope is falling down from Anna's perspective and Poncho is warning her.

The object visible under the log while Mac and the major are hiding there, which looked like a microphone to some, has been identified as the ends of two guns.

Anna swings a branch at the right side of Poncho's head, but he turns before the impact, which is why he bleeds from the left.

Dutch and his men can "choose" missions because the movie establishes them as former military. They are contracted for a job, and they obviously still know their former superiors (like the general at the start of the movie). Once they accept a job they are bound to follow it through and essentially also become "expendable assets".

There are a lot of common house plants in the jungle, some still in their black plastic pots. Near the end, for example, when they start to go to the chopper.

When the Predator picks up the scorpion, its infrared imaging shows the arthropod as warm and then cooling off rapidly; Scorpions however are cold blooded to begin with, and even what little body heat it'd possess would have cooled off long before the Predator picks it up.

When the crew are in the chopper traveling into the jungle 'Long Tall Sally' is playing on the tape recorder behind Blain - but there is no tape in the recorder.

When Mac asks Dillon to "turn around" so he can remove a scorpion from his back with his knife, the material used to fix the live scorpion to the knife can clearly be seen.

In the early scenes when Dutch's crew attacks the enemy camp and specifically just prior to engaging the helicopter, the pilot jumps into the helicopter and tries to shut the door. The door begins to fall off the helicopter revealing that it is only a flimsy set piece rather than a real helicopter.

When Anna hits Poncho and runs away, Dutch points and "whistles" at Hawkins ordering him to chase Anna. But when the whistling noise is heard Dutch's mouth is closed.

When Anna sneaks up on Dutch from behind in the rebel camp, he turns around at the sound of a pistol being cocked, when she is merely holding the gun.

When Dutch is running from the Predator, and trying to lead the beast into the small tunnel which contains the "trap", a quick cut-away shot of the trap mechanism appears to be a photo of the trap, as opposed to "live" footage, and even appears to be a bit out of focus.

When Dutch is told that the craft found "looks like a surveillance bird" the words don't match the lip movement.

As the Predator walks across the wooden 'bridge' that Dutch hides under, his footsteps clearly make the sound of the solid wooden heels of very normal human shoes.

Anna sneaks up behind Dutch with a gun. Dutch then hits Anna on the side of the head with his gun. If you look in the lower left corner of the screen, right when Anna is about to fall, you can see someone's hand touch Anna's back to help her "fall" to the ground. (Non-widescreen version only).

In the pan-and-scan version, when Billy first finds the bodies of the skinned green berets, he is startled by the vultures as they fly away. In a quick overhead shot, a camera can clearly be seen below him.

When Dutch and his team raid the guerrilla camp, they are still looking for hostages, as they only know for certain that one of the captives has been executed (the one shot by the Russian advisor). Yet during their assault, they virtually raze the camp with reckless abandon, blowing up entire buildings without ever bothering to check if the hostages might be inside. It isn't until after the firefight that Mac bothers to look for the men they are there to rescue.

This has been listed as a plot hole although whilst potentially a character mistake it isn't a plot hole. The plot of the movie isn't broken because of the way the team attack the camp. All the hostages were dead anyway (even though the team didn't know it at the time), so in the end it didn't matter.

When the Predator kills Blain, the energy blast hits him in the back and goes through his entire body, exiting his chest cavity. This would have gone through the ammo canister carried on his back, which would have rendered his mini-gun inoperable.

The Predator is shown to use thermal-imaging to track its targets; several times people's bodies appear as bright orange/red against a blue background. However, the temperature of the jungle they're in would be near or above a human's body temperature, so there would be no discernible difference in a thermal image between a person and their surroundings.

Although Dutch's body was covered in mud, his eyes never were. Eyes give also off a lot of heat, so the Predator could have seen him.

The extraction point seems to be ridiculously distant from the guerrilla encampment. Assuming that the pilots and mission planners knew or suspected that hostages might be retrieved from camp, it seems to be rather illogical for the extraction point to be more than a few miles away from that camp as the group has neither wheeled vehicles , nor pack animals, to increase their speed or range. Even if the film presumes that the "area was full of guerrillas" (which was stated, but never shown) the longer Dutch's group stayed on the ground, the greater the risk was that they would encounter those guerrillas. The group should have reached the extraction point at a time period well before they encountered The Predator.

When 'Dutch' and Major George Dillon are hiding from the Predator in the hole/trench the boom mic is visible.

When Dillon radios for help, the voice on the other end says they will speak again at 9:30 hours. Dillon incorrectly acknowledges it as 10:30 hours.

After the attack on the guerilla camp is over Dutch orders Mac to 'Clear the area, no traces' then throws his coat on the ground and leaves it behind as he approaches Billy to discuss 'a way out of this hole'

Billy is supposed to be a keen tracker, yet when he initially discovers the bodies of the green berets, he is caught completely by surprise upon seeing them once the foliage is removed despite the fact that the bodies were still rotting, the scent of which he should have easily picked up well beforehand.

When Dillon is requesting extraction over the radio, he says, "Blazer one, I repeat, extraction necessary." The word repeat is never used in that context in the U.S. Military. Instead of "repeat", "say again" is used. Dillon actually gets it right in his next sentence, "Say again Blazer one, say again."

When he looks at Hopper's dog tag, Arnold says, "Jim Hopper." But in close-up the dog tag reads "C E Hopper."
