Continuity mistake: In the opening scene with the three helicopters, there is only one chopper with missile launchers on it. But soon on all of them have launchers and in the immediate next rear-view shot, voila, no launchers. They keep appearing and disappearing during the whole action sequence. (00:05:15)
Continuity mistake: At the start, the dirt and grime on the shotgun Cartridge in the one man's hat keeps changing. (00:07:25)
Continuity mistake: When Cockburn is at the beach and sits down with Four Leaf, Four Leaf says "Beds give me nightmares". At that point, Four Leaf doesn't have his cigar in his mouth, but in the next shot the cigar appears in his mouth. (00:21:10)
Other mistake: After the part where Cockburn explodes to bits on a mine, Speedman finds and picks up his walkie talkie as Cody is trying to communicate through it. The device is not only smoldering hot, causing Speedman to have to drop it, but it even appears to be melted. With the amount of heat it went though, much less the jar of the explosion, it should not have been still working at all. The 'actors' should not have heard Cody though it. Not only this, but the establishing shot of it on the ground shows the antenna snapped and broken over. (00:29:50)
Continuity mistake: Just after the ambush scene, Speedman walks towards Lazarus and speaks to him, the camera viewing from behind Speedman's point of view. The very next shot shows it from behind Lazarus with Lazarus looking back in suspicion. There is a noticeable difference in the level of day light between these shots. Like an hour has passed with the sun going down. (00:33:20)
Continuity mistake: When Tugg Speedman is talking to Kirk Lazarus, Tugg Speedman uniform has a large metal caribiner on his right shoulder. In between shots of him talking to Kirk Lazarus, the caribiner switches orientation from facing left to facing right to left again. (00:36:40)
Continuity mistake: When Ben Stiller is talking to Robert Downey Jr. about his performance in Simple Jack, the backpack strap on his right shoulder is sometimes over the carabina and sometimes beside it between shots. (00:36:45)
Continuity mistake: When Kirk Lazarus tricks Tugg Speedman into giving him the map, in one shot one of the shotgun shells on his back in his artillery belt is out of place and not lined up with the rest of them. In the very next shot, all the shotgun shells are lined up and in place evenly. (00:44:05)
Continuity mistake: When Tugg Speedman leaves the team, when he is climbing a hill his rifle is on his back, but in the next shot he is holding the rifle while climbing. (00:45:00)
Continuity mistake: When Speedman is by himself in the rain, he puts down the iPod and picks up the Chapstick with the white cap on. The next shot, the cap is off. (00:49:00)
Factual error: Pandas do not roam in Southeast Asian jungles. (00:50:10)
Continuity mistake: When the actors (minus Tugg Speedman) have set up camp for the night, close up shots of Kirk Lazarus show him petting the water buffalo, while all other shots show the water buffalo completely out of arm's length. Lazarus does not move around in this scene to make this possible. (01:15:20)
Continuity mistake: When Tugg is in his room after giving his "Simple Jack" performance for the Vietnamese, he splashes water on his face to remove his make-up. Cut camera angle to him looking up when his friends burst in, and his face is completely dry. (01:23:55)
Revealing mistake: During the helicopter escape scene before Tran fires the rocket at them, you can see Cody's hair showing up a bright green from the green screening. You see it several times, but most pronounced at the moment he and Portnoy see Peck arrive with the TiVo. (01:36:10)
Suggested correction: Actually it's from the overhead Plexiglas windows in the Huey. They are tinted green to cut down on sunshine. Any light shining in from above is going to make things appear green.
Continuity mistake: When Jeff Portnoy is tied to the tree, he changes from having trousers to having just Y-fronts on several times. Usually happens between shots of the group and shots of just him.
Continuity mistake: In some of the earlier shots from inside the drug maker's camp, you can see a set of high-tension power lines running across the sky, but in the establishing shots, it's only jungle.
Continuity mistake: Throughout the movie, Peck's hair fluctuates in volume quite a bit.
Factual error: The rocket that little Tran fired at the helicopter towards the climax travels much too slowly. Peck would not have had time to react to it if it moved at a proper speed, much less throw a heavy mechanical device through the air to intercept.
Plot hole: In the scene where Speedman and Lazarus are discussing their acting and Lazarus tells him to never go full retard. It shows these two leading the group, however they stop and talk for quite a while, and the rest of the group are nowhere to be seen until Speedman and Lazarus start moving again. The group finally caught up with them. If at this time, Speedman was still leading the way with the map, how could the group even find these two after being left behind enough distance that this conversation could take place?
Factual error: In the helicopter scene at the end of the movie, after the RPG is launched at the Huey Helicopter, Danny McBride pulls back violently on the cyclic stick between his legs to avoid the rocket, but instead of moving backwards, the helicopter ascends in altitude, which would only happen when the pilot pulls up on the collective stick, located on his left. Pulling back on the cyclic with that amount of force would have certainly caused the helicopter to crash into the trees located behind the aircraft.
