Other mistake: When Dolph Lundren shoots his boss he shoots him through his glasses in his eye. However the guys lens never breaks. His glasses fill up from the inside with blood. (00:52:50)
Other mistake: When Ivan Ooze gives out those slimes to the kids, that boy is at the very back of that big crowd. As Ivan Ooze starts giving them out, it switches to the boy and he already has some slime, but it would have taken a few minutes for him to get one. (00:42:00)
Other mistake: When Superman and Lois are flying through the clouds, there are a number of shots in which we see Superman from Lois' point of view. If you look closely, you can see that Christopher Reeve is not being suspended in these shots, but is, in fact, kneeling to look as though he is flying. You can tell by the profile of the red trunks.
Other mistake: When Woods gets shot by the nails fired by the small robot, the amount of blood in his sweater keeps changing during the following scenes.
Other mistake: The same front shot of Superman flying is used over and over and over again.
Other mistake: In the scene when Robert gets caught up in the trap by Grand Central Terminal, there are no traffic lights on the upper street that they show him being suspended from.
Other mistake: Due to the gait of the T-Rex, its head moves rather significantly when it walks as seen throughout the movie. However when it approaches Dr. Marshall with the laser in its teeth, the laser is steady and able to pinpoint a line up his head in a very steady manner which would not have been possible.
Other mistake: Wolverine shields Yashida from the blast, burning off all his hair. Somehow his pants manage to remain unaffected by this, as seen later when they are climbing from the pit.
Other mistake: When encased in rock, George lights a match to see the current time dial on his machine. But the dial is backlit every other time its shown.
Other mistake: Bruce is seen wearing a Polar F5 heart rate monitor in a couple of scenes after Betty gives it to him (such as when he is in bed with Betty) but there is no transmitter strap around his chest, which that model needs in order to pick up the wearer's heart rate.
Other mistake: When Amy Adams leaves the spacecraft for the final time she is met by Jeremy Renner who throws a blanket around her shoulders. As he does so, the blanket gets caught on something out of view top-of-frame (presumably a boom mic) and he has to tug at it to free it. This was part of one long take in fading light and given the amount of background action going on it was presumably too difficult or time consuming to re-shoot. (01:32:55)
Other mistake: When Helen turns right to "head to the stacks" everyone in the back of the van falls to the right. Centrifugal force would push them to the left. (01:56:06)
Other mistake: The extras in the shot where Zed pulls the cart through the courtyard of apathetic are the same extras used in the shot where he pulls into a barn. Even if they could move, that's awfully quick. These people are supposed to be zombies. (00:38:00)
Other mistake: In the scene where Dr. Isaacs is in the teleconference with the Umbrella Board of Directors, there are several glasses of water sitting in front of each individual hologram. At the end of the teleconference, the holograms of the board members disappear, but none of the glasses follow suit. This tells us that the glasses of water were physically in the room with Dr. Isaacs, for absolutely no reason, given all the other attendees weren't really there. (00:17:40)
Other mistake: Just after Rico and Ace rescue Carmen, the other guy has hold of the nuke, which explodes. Watch when the rocks collapse behind the three characters, you can see a nice square block lower from the ceiling, almost like a door being lowered. The crew could perhaps have made it look a little more realistic. (01:55:00)
Other mistake: When Kate is viewing the T-X on the security cameras, the two views of the corridor do not match each other. For example, the first camera shows glass walls, whereas the second shows wall panels. (00:23:30)
Other mistake: During the eye exam, Daryl recites the eye chart but does not get it correct.
Other mistake: We know that the blob dissolves flesh and hair and that it can also burn wood (since fluid coming from the blob burns a small spot on the desk in the hospital) and that it can dissolve bullets, but despite this obvious acidic state, the blob doesn't dissolve plants, walls, glass, concrete, metal, nor sticks and twigs.
Suggested correction: It can control its functions otherwise it wouldn't be able to exist.
Other mistake: When He-Man is fighting against the centurions on the floating disks, he tells the others to get inside a building. As he opens the door to the building, not only does it fall right off the hinges, but his sword also falls right off his back, pulling his cape off with it just as the scene ends. (01:09:20)
Other mistake: When Polly notices the reflection of Joe's airplane marking on the water, the code "hllod" gives "Polly." That's impossible. To get "polly" from "hllod," a person would have to rotate the word 180 degrees, not view it as a mirror reflection.
