Revealing mistake: During the rooftop rescue, when Morpheus is hanging from Neo's arm (who is hanging from the helicopter), a safety wire is visible running out of Morpheus' sleeve and into Neo's hand. (01:45:48)
Revealing mistake: When Qui-Gon, Jar-Jar, and Padme are eating at Anakin's house, Anakin's mum pours water for Qui-Gon. But when she gets to Jar-Jar, she tips the pitcher but no water comes out. (00:39:10)
Revealing mistake: When the bridge is exploding from the mine attack, the stuntman playing Jason obviously launches himself out of the captain's chair.
Revealing mistake: When the Japanese tanks are firing upon Godzilla, one of the pyro effects catches the Godzilla suit on fire (at the arm). One can see the stunt man begin to frantically shake his arm upon this realization before the editing cuts to another shot.
Revealing mistake: When the Interceptor team flies in their cargo plane to Mexico to investigate the UFO crash, several shots filmed from the front show the six of them all in the cockpit (not in the body of the plane.) They're seated as they might be in a car, three across, front and back. The window of the cockpit looks remarkably similar to a station wagon windshield, down to the large rectangular front windshield, and even the rear view mirror is in place.
Revealing mistake: In the scene where Will Smith first jumps aboard the rear of Loveless's train, as he climbs onto the roof of it you can see contrails from a jet aeroplane in the sky (top left).
Revealing mistake: When Jamie Lee Curtis falls into the fuel tanks, how could she be breathing? The gases would be too toxic for her to breath, and wouldn't she be blinded by the fuel?
Revealing mistake: When Sly breaks the board you can tell it was already broken.
Revealing mistake: Part of the control panel for the hypersleep pods is just a flat flashlight (I used to own one, I think it was made by Polaroid) with the manufacturer's name covered over. When the panel is being used, the flashlight's button is pushed and it turns on.
Revealing mistake: When Beowulf is fighting Grendel in the sanctuary and is climbing up into the rafters, his black support wire is visible. (00:44:10)
Revealing mistake: Jude Law is inside the game and he's supposed to be American. When he finds out that his bio-port has been infected he says his next line in his normal British accent. (01:20:10)
Revealing mistake: Pnub's (Elden Henson) head in the scene where Anton kills the two cops is obviously animatronic, it's eyes are clear blue and Pnub's eyes are brown.
Revealing mistake: In addition to the chain and lock not being in a position to actually secure the entrance to the "Metro Christian Shelter", the board covering the entrance does not appear to be securely attached to the building on the right side. Furthermore, when the men move the board over, it is a rather thin piece of plywood/board that can easily be kicked in. (00:17:17)
Revealing mistake: At the end of the film, the screw is tapping on the window to get out and Hogarth moves to put the box down. The box completely vanishes from the shot for a few frames towards the end of the shot.
