Plot hole: In the pre-title sequence, James Bond travels in a hovercraft along the dirt road, which is full of landmines. Soon after reaching the waterfall at the end, trucks drive up along the road he just drove in on to capture him. As there was only one road into the waterfall complex, the landmines must have all disappeared, as earlier on in that sequence, we are informed that the only way that the North Koreans can avoid the mines along that road is by hovercraft. (00:12:05)
Plot hole: When Amidala and some of the clone troopers get blown out of the ship chasing Dooku, later the trooper approaches Amidala and asks about making their way back to the front lines, but Amidala says they should go to the hangar to help Obi-Wan and Anakin. How did she know about the hangar, having left the ship quite some time before it arrived at the final destination? (02:05:50)
Plot hole: In the Ice Tunnel scene, Manny, Sid, and Diego come to a stop on the vertical block of ice. It breaks, and they slide through a 'field' of icicles sticking out of the ground. Their 'sled' is shaved down to nothing, indicating that the icicles are sharp. After going through the same tunnel as the baby, how did the baby make it through that field? (00:46:53)
Suggested correction: A possible reason for the sled slowing down is not due to the ice tunnel but the sheer several tons of weight the sled had on it while it was sliding through the tunnel.
Good point. Without the weight, the icicles would had slowed down the sled instead. And since the baby hardly weighs anything at all, it wouldn't have been able to slide through the field, it would've just collided with the front icicles and stayed there. But it still leads back to question of how the baby got through the field.
Not true, their "sled" is destroyed by the icicles.
Plot hole: In Paris, why does the assassin go to the ridiculous amount of trouble of swinging into the room on a rope with a machine gun when he came in from the lobby (as proved by the dead woman downstairs)? Alternatively, if his intention was always to surprise Bourne by coming in through the window, why venture downstairs at all? (00:44:07)
Plot hole: At the beginning of the movie, Hedwig rattles her cage, and Harry says apologetically, "I can't let you out, Hedwig; I'm not allowed to use magic outside of school." But he wouldn't have to use magic to let her out - the key is visible sticking out of the lock on the cage, so all he would have to do is turn the key. (00:01:10)
Plot hole: At the end, there is an explosion large enough to destroy and sink an entire ocean liner, but Julianna Margulies, who was sitting right next to where the explosion went off, not only lives, but is virtually unscathed? Yeah, right. (01:19:00 - 01:20:35)
Plot hole: When Marty Wolf comes out of the pool he is blue from head to toe yet with all the swinging of his hands and dancing, let alone the mirrors in the hall, he does not notice he is blue until he has put orange dye in his hair. How could he miss it?
Plot hole: During the boxing match where Eddie Murphy is wearing the special contact lenses, he sees that Owen Wilson's life is in danger. So much so, that he rushes out of the ring instead of doing his usual grand-standing. But when he shows up at the tower to rescue Owen, he has on pants and a shirt. I guess he figured Owen could hold out long enough for him to get dressed?
Plot hole: When Xander is driving onto the bridge, chased by the police cars, we see that there are police cars also blocking the end of the bridge to stop him getting away. How come none of them noticed the ruddy great ramp sitting alone in the middle of the bridge and moved it? It wouldn't take a genius to work out what he might do.
Plot hole: There is supposed to be no power when the Dragonfly ship reaches the island, but the lights are still on. At first, I thought it was just a lighting trick, but you can see the lights are on in the tunnels.
Plot hole: During the nova scene, everyone is tying down the sails after securing themselves with lifelines to the mast. Jim and Silver are on the front and Silver is knocked off. Jim is then all dramatic and runs to grab Silver's lifeline which seems to be coming from above, and pulls Silver up like a pulley. How come? The lifelines were attached to the mast, so Jim's action is pointless... even if he could do it, because a shot later both lifelines are streaming right to the mast, leaving no room for a pulley of any sort.
Plot hole: Holmes asks what had frightened Sir Charles enough to make him run away from the house. But when Dr. Mortimer described the scene, he only mentioned that at one point the prints did not show heel imprints. It is an easy deduction that sir Charles had been running, but the doctor did not say anything about the direction of the footprints.
Plot hole: When Sullivan shoots Connor Rooney at the end, he flicks the door and we see the dead body. However the wall and some of the floor have loads of dried blood on it when he was only shot seconds before.
Plot hole: When Nameless and Flying Snow are fending off the arrows, the arrows blocked by the two seem to be the only arrows coming toward the school, as there are no arrows flying beyond their reach (omitting the ones missing the school entirely).
Plot hole: Although the errand bird always insists on the postage and even asks for additional fees for more than twenty words, he never gets any payment from the assigning characters.
Plot hole: When Austin and his father Nigel disagree as to how to proceed after Goldmember gets away, they part ways. So why does Austin take his father's car? (01:06:25)
Plot hole: When Alexander is traveling into the future and goes through the ice age he is visibly affected by the extreme cold temperature outside the time bubble. However when he stops in the future when the moon had been destroyed then continues he is not affected by the explosions and extreme heat around him. Based on the effect the extreme cold had on him (frost on his face and hair) he should have been roasted alive.
Plot hole: Throughout the movie, the flies are vulnerable to light (direct sunlight and even lightbulbs) to the point of incinerating in a split second. Except... they are not; in several sequences they fly to and from bodies and without even taking a direct path (look at all the action happening in front of the house, by the cars, in broad daylight).
