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.

Trivia: In the movie, Robert Downey Jr.'s character of Kirk Lazarus, who is in character as Lincoln Osiris, says he won't drop character until after the DVD commentary. In the DVD commentary Robert Downey Jr. actually stays in character as Lincoln Osiris until the scene where Kirk Lazarus also drops the character. At this point in the commentary, Downey Jr. adopts Lazarus' "real" Australian accent and stays in that character.

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)

Continuity mistake: Throughout the movie, Peck's hair fluctuates in volume quite a bit.

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?

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)

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)
