Continuity: The level of orange juice in Mariana's glass when Beck talks to her at the bar
Continuity: The tears in Beck's shirt where the baboon clawed him switch sides after the truck explodes during the final fight (flipped shot)
Continuity: In the final fight scene between Beck and Hatcher, you notice that Hatcher has no bullet wounds on his shirt sleeves. When Mariana shoots Hatcher in his right arm, he grasps his bicep. However, the "bullet holes" in his shirt appear near the elbow. Also, Beck shoots the pistol from Hatcher's right hand without hitting his body. In subsequent scenes during Hatcher's final dialog, Hatcher's shirt has an identical wound on his left arm, with no one having shot him.
Audio/visual unsynchronized: Just before the bulls come charging into the town, you hear glass bottles clinking together, but they are plastic in the close-up.
Audio/visual unsynchronized: When Beck and Travis are swinging upside down, they are talking but their mouths aren't moving.
Errors in geography: Beck and Travis were attacked by African baboons.
Continuity: In the bar, Beck handcuffs Travis when he is on the ground face down. We then see Beck pulling Travis up off his back by his shirt front.
Continuity: The fruit that Beck and Travis ate in the jungle was completely different to the fruit that Beck gave Travis' father and his goons. The fruit they eat is actually a regular cheremoya.
Continuity: When The Rock walks into the bar at the start of the movie he puts his sunglasses in his inside jacket pocket. In the next shot, he does it again.
Continuity: After the first fight, Beck sets the bag of frozen peas down and it moves to the other end of the table between shots.
Continuity: When Beck first captures Travis and they're escaping by jeep, an overhead shot shows Travis's hands resting on top of the windshield. But the next shot from the hood shows his hands in his lap.
Continuity: When the jeep falls off the cliff, the shot right before it hits the water has the jeep leaning forward (about to hit the water hood first,) but in the next shot it lands flat.
Continuity: When Beck, Mariana, and Travis swim underneath the waterfall, Beck swims with his shirt on. Shortly after he gets out of the water, his shirt is dry.
Audio/visual unsynchronized: When Declan is driving Beck into El Dorado, they stop for a truck full of rebels and Declan explains who they are. In a close-up of Declan, his mouth is moving but he's saying something completely different from what we hear.
Continuity: When Beck is walking away from the exploding bus, the cuts on his chest are on the opposite side.
Continuity: When Beck has hit one of the bad guys with the two shotguns he then grabs one of them and puts them through his arms and then cocks them. He then pushes the guy forward into the other guy but on the next view of the same action the guns have turned around with the barrels pointing behind him.
Audio/visual unsynchronized: During the fight between Beck and the head Kontiki rebel, each pass of the rebel's knife sounds a "shwing" as if scraping metal; even while completely missing Beck's FLESH.
Revealing mistakes: Obvious doubles when Declan and Beck drive past the "Helldorado" sign.
Revealing mistakes: Obvious stunt doubles when Beck and Travis are falling down the cliff.
Continuity: When Beck, Travis, and Mariana are riding in the boat and she attempts to shoot him, there is a huge patch of algae on Travis's left. The next time we see that side of the boat it is gone.
Continuity: When Beck, Travis, and Mariana are done with their boat ride, Mariana starts talking to Beck. The two bruises on Beck's neck disappear between shots.
Continuity: When Mariana, Beck, and Travis are in the boat, we see Mariana turn to look at Travis twice.
Continuity: When Beck is shot with the beanbag gun, he recoils from the first beanbag *before* it hits him.
Factual errors: All the characters speak Portuguese so badly that sometimes it's impossible to understand what they are actually saying.
Revealing mistakes: When Beck is talking with Travis' Dad, the Dad has a cloth on his shoulder. Firstly the cloth changes in position from shots but also in one shot he hasn't got it on, then in the next it's back on again.
Continuity: When Beck punches out the camera in outpost 1 the tattoos on his right hand fingers are gone.
Errors made by characters (possibly deliberate errors by the filmmakers): When Travis goes to the washroom in the jungle he never zips himself back up!
Errors made by characters (possibly deliberate errors by the filmmakers): At the end, Beck drops his bag to fight Travis, then when they walk away he never picks it back up.
Errors made by characters (possibly deliberate errors by the filmmakers): When Mariana lifts the gold statue without any effort it is obvious that it is a fake. The weight of gold is a lot (19,3 g/cm3), so that "Gato"'s weight is at least 20kg.
Continuity: During the bus explosion, the force pushes you away from the bus (see Travis), but Beck's shirt is blowing in the wind towards the bus.
