Revealing mistake: When the military security checks Flash's phony badge, the name on the personnel list to the right does not match the fake identity; Barry's false identity is "Rowe, Wesley", but in the list the name "Band, Ryan" is highlighted. This mistake was not present in the theatrical 'Whedon' cut where the name was altered to match. (02:27:05)
Revealing mistake: When Bloodsport rescues Ratcatcher 2 from on top of the car, they don't actually dodge the arm coming for them but are going straight through like it's not even there. (01:54:16)
Revealing mistake: The back of Cletus Kasady's head appear quite different between the semi-POV shot in the car (stunt driver) and the next shot when Woody Harrelson steps out of it and gets to the gas station where he will 'hack the internets'. (00:49:40)
Revealing mistake: Based on the size of the dinosaur's back shown behind the 6' high cement enclosure, there is not enough room for the rest of the dinosaur's tail and the enclosure is not high enough to accommodate its neck and head. (00:16:29)
Revealing mistake: Each time Julia lifted the roof window on the camper, it was flush with the roof (like a sun or moon roof). However, two individual shots of that area showed a raised section about a foot high with two windows on one side - totally different from the flat roof window. An aerial view of the roof did not indicate that these were in different areas of the roof. (00:52:20 - 00:55:03)
Revealing mistake: Some views of Malik driving show him, as well as Jay in the back seat, on the opposite side of the car (mirror image). (00:36:55)
Revealing mistake: When Paul and his father Leto are walking through the field between storage bins/sheds, the sheds are largely situated perpendicular to their path. After they stop walking, the angle of the shed behind them shifts to being roughly horizontal to their path. A front shot of Paul still shows a shed on the opposite side as being perpendicular. The background also changes to blurred, still images of dried grass (with no light breeze). (00:14:09 - 00:14:43)
Revealing mistake: The rear of the steer's carcass was on fire and smoldering, but wasn't seconds later in the aerial view. Also in the aerial view, the position of the steer relative to Alexander was different. (00:06:00)
Revealing mistake: While Martin is being mauled on the ground by Valentine the zombie tiger, he is being thrown up and down and side to side. There are a few seconds where the tiger takes a small break and watches him try to crawl away, but his body is still swaying around as if he still being grabbed by the tiger, but the tiger is not touching him; they did not match the animations of the tiger with the physical acting of the actor properly.
