Visible crew/equipment: In a scene towards the end, you can see the two bad guys flip into the air, and see the air ramps they fly off. (01:13:24)
Revealing mistake: The scene with the shack has many mistakes, but only if you play it in slow-mo. First, he throws the circular saw at the guy in the window, the saw is moving on wires and he has a hairpiece someone just pulls off with a wire. The next guy he stabs with a pitchfork, and Arnie just lightly stabs him and the guy falls forward holding onto the pitchfork to make it look as though he was stabbed. Arnie then throws a saw at a guy hitting him in the chest. The guy actually just catches the saw in his arms in a way to make you think he got hit. Then Arnie swings some sort of gardening tool into the genitles of a man, but he actually stops it before it hits the guy and the thug just holds onto the handle. Finally, Arnie hacks off the forearm of a another man. You can tell that his arm was fake from the elbow on. (01:15:15)
Continuity mistake: During the attack on El Presidentes house Matrix is seen using the belt fed machine gun. One shot shows him firing it apparently left handed (the film has been flipped as mentioned before) with a strap diagonally across his chest. The shots immediately before and after this he does not have the strap. A couple of shots later he is seen picking up a gun with a strap and putting it over his head. The next shot is the same one as previous but flipped back to its correct way. (01:15:33)
Continuity mistake: During the ridiculously overdrawn action sequence at the end, Arnie has a belt-fed machine gun which becomes lefty and righty through certain shots. Since Arnie isn't lefty, and it's unlikely that the army would just have a lefty belt-fed gun lying around, it's safe to say that the picture was reversed. (01:15:33)
Continuity mistake: Towards the end Arnold is firing a gun, and the length of the ammo belt changes. They show the ammo almost gone and then after an edit it's dragging on the ground. (01:16:00)
Continuity mistake: During the machine gun scene at the en Matrix has a belt fed M60 machine gun. When the fight starts, he has plenty of bullets. A few seconds later he has about 20 cm length of the bullet belt left. Scene switch - and he has more bullets. This switch between low and high ammo a few times. (01:16:15)
Continuity mistake: When Bennett holds his knife against Matrix's face the knife keeps swapping positions and also the blade appears up or down depending on the shot; despite Bennett being unable to move his arm. (01:18:10)
Audio problem: Towards the end there's a firefight between Matrix who wields a shotgun and El Presidente who is armed with a Steyr AUG. The weapon sounds used for the Steyr AUG however are from a MAC 10 or an UZI and don't sound a bit like it. (01:18:13)
Continuity mistake: During the last fight, when Bennett and Matrix fall over on the platform, the gun on the floor to the right side of the screen moves around between shots, allowing for Bennett to easily pick it up. (01:18:20)
Other mistake: Bennett grabs the furnace door but doesn't get burned. (01:18:30)
Continuity mistake: When Bennet and Matrix are fighting at the end. Bennet has his hand over Matrix's face. During instant camera cuts, the position of his hand alters on Matrix's face and neck. (01:18:55)
Audio problem: The scene where Bennet and Matrix are fighting towards the end of the movie, before Matrix kills Bennet they have each others throat in their hands and one of their backs is against the furnace. While they are grunting and groaning, if you listen carefully, you can hear one of them say "switch" just before they change positions. (01:19:05)
Continuity mistake: When Arnold throws the pipe at Bennett the end of it is round and clean; in the following shot it is irregular shaped and edgy. (01:20:00)
Continuity mistake: At the very end of the film. When the 3 helicopters and the seaplane come into land, it is quite a wide shot, with no boats visible. A few minutes later, when the seaplane takes off again, a big white boat is near the coast. Even if the boat was off camera during the landing scene, a few minutes was surely not enough to get that far, and that close to the shore. (01:20:30)
Continuity mistake: At the end when Alyssa Milano is standing next to Arnold, in the wide shot you can see it's him, but in the close-up of Alyssa the person standing next to her has blond hair on his chest while Arnold is well "shaved clean". (01:21:30)
Continuity mistake: When Matrix is fighting with Bennet at the end of the film with the knifes, when Matrix slashes Bennet's wrist if you look at the knife it has no blood on it. (01:22:00)
Continuity mistake: When Bennett is beating the crap out of Matrix by the furnace, the close shots show big bleeding wounds, which disappear or diminish drastically in the wide shot. (01:22:25)
Continuity mistake: In the fight scene where Matrix and Bennett are trying to force each other against the furnace, watch Bennett's hands as he struggles with Matix. In one shot Bennett has his hand pressing against Matrix's face, in the reverse shot he is holding Matix by the back of his head/hair. His hands switch back and forth several times. (01:23:00)
Continuity mistake: During the fight at the end of the movie between Matrix and Bennett when Bennett calls Matrix a "dead man" and he responds with "Bullshit" you see him come off the wall with his left hand. He is throwing a left hook, but in the very next shot when the punch comes in contact with Bennett his fist is going from right to left in a backfist motion, rather than a left to right hook. (01:23:45)
Revealing mistake: At the end of the fight between Matrix and Bennett, Matrix throws a pipe through his body into the steam duct behind him. However, immediately after he is pierced by the pipe, we see Bennett slide about half a foot down the wall, which would be impossible with the pipe lodged in behind him. (01:24:00)
