Revealing mistake: When Peter Parker first discovers he can climb up walls (while in citizen clothing), he tests it out by climbing up a building in an alley. During this scene, you can clearly see his clothes hanging out forwards, indicating that the scene was filmed with him crawling along a floor horizontally. (00:24:50)
Revealing mistake: When Amidala and Anakin are eating and he cuts her a piece of the fruit and "floats" it back to her, the bite appears in the fruit a split second before she actually eats it. [This appears to be fixed in rereleased versions]. (00:53:40)
Revealing mistake: There is a shot right after the first time the clerics are entering the city from the nethers that you see an APC patrolling the wall road above the entrance. In that shot two shadows are being cast on the road. As the CGI APC passes through them they simply don't cast a shadow on it as they should. (00:08:40)
Revealing mistake: When the group is being attacked in dining hall B, they are trying to get the doors open. J.D. is firing at two zombies and turns away to open the doors himself because Kaplan keeps forgetting the code. If you look closely, one of the zombies reacts a second late from being shot down. (00:44:40)
Revealing mistake: When the megalodon attacks the yacht the party goers jump off the yacht, and some of them reach the large round safety raft. To the raft's right, there is a visible yellow line attached to it so it doesn't drift away for the shots.
Revealing mistake: When the camera pans up to show Manchester on fire, flashing lights are just visible on the horizon in the middle of the road. This is the police keeping the traffic back so the scene could be filmed.
Revealing mistake: Near the end of the film, when Picard bends the pole down to stab Shinzon, the pole supposedly goes through him and out the other side, but the prop travels several inches down his waist. A shot later, you can see the prop pushing against Shinzon's clothing, obviously not piercing anything. (01:39:17)
Revealing mistake: When Becky meets Simon in the cube, they hug, then Simon literally stabs Becky in the back. As she falls down to the floor, her black shirt reveals not only some of her chest, but part of a black microphone wire. (01:15:15)
Revealing mistake: At the scene where all the spy kids are fighting the waiters, watch Gary as he is fighting. The waiter he is fighting throws him back, but then Gary activates his rockets shoes. Yet to activate those shoes you have to tap them together. The rocket shoes activate a few seconds before Gary tapped his heels together.
Revealing mistake: Just after Zak realizes the power of his watch, he and Francesca ride off into the town square and pass a Los Angeles transit bus. In the same town later that evening, as Zak and Doppler are being pursued by the evil operatives, they disengage the hyper-time, and just barely miss a head on collision with a New York MTA bus. (00:33:15 - 00:48:55)
Revealing mistake: In the scene where Jennifer Love Hewitt and Jackie Chan are on the top of the building, trying to plant the bug on the briefcase, and the men all attack, as Jackie is hanging over the edge Jennifer has a man on his knees. If you watch closely, or in slow mo, she is about two feet away from actually hitting the guy.
Revealing mistake: When Alex uses his time machine for the last time to destroy the Morlocks, watch the closeup of his machine when it's activated. In the lower left hand side of the machine you'll see Alex's laboratory in the background. This is confirmed by director Simon Wells himself in the DVD commentary.
Revealing mistake: When the two main characters explode and then implode near the end, you can see that some of the debris being sucked in are passing "through" various other objects, revealing they are computer generated.
Revealing mistake: When John goes to close Gordon's eyes, as he lowers his hand, you can see him close his eyes on his own.
Revealing mistake: When Simone is performing in concert, the auditorium is supposed to be packed full. But when the camera flies over the audience, in the background you can see empty space because only about 100 extras were recruited for the audience. (01:04:00)
Revealing mistake: It's nice to see that Alex (the helicopter pilot), is able to keep herself in such nice and kempt condition. Look at her... clean, washed and combed hair, makeup, and she's actually got lipstick on in one of the scenes.
Revealing mistake: When the boy runs from the jumping spider he crosses the road, which makes the eighteen wheeler lose control and it jacknifes. You can clearly see a set of tyres are moving with the right direction of the truck, and there are a set of tyres sliding. (00:40:55)
Revealing mistake: When Anderton first sees himself killing Leo Crow in the precog vision, pay attention to the shot when he says "no". The reflection of Jad in the Hi Tech screen doesn't match with his movements.
Revealing mistake: When Jay is at the post office looking for Kay, he's talking to him in the parking lot and Kay is sitting in a mailman's cart. Jay says something to Kay, and Kay punches him, but you can see that he didn't touch him, especially since Jay reacts to the hit a split second before it happens. (00:28:45)
Revealing mistake: When the doctor intercoms the colonel because he cannot get into the medical room for the pregnant woman having nightmares, the camera shows the intercom, which is simply the back end of a desktop computer with a couple of knobs stuck on it. (00:24:50)
