Plot hole: Anderton's wife gains entry into the jailhouse using her husband's eyeball - but he's already locked up inside, so his eye would not still have access to enter as it pleased. Any place anywhere that would have any sort of security system requiring anything from a simple passcode to a card key to a retinal scan, would immediately delete the user in such instances from all rights. And would also certainly report on any attempted use of such (retinal scan, pass code, whatever). (02:00:45)
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: When Frank Martin steals the Mercedes, how does Lai manage to open the rear door, get in the back and hide - all with her hands bound behind an office chair? Not to mention actually closing the door and hiding herself (and the chair) in the rear footwell long enough for Frank to drive off and not notice her until they are out on the road. (00:29:25)
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: When the President of the United States attends a public gathering (such as the SuperBowl) the level of security is extremely high. So why wasn't Mason's delivery on the day of the game checked for explosive devices?
Plot hole: The Americans allegedly landed at Manchester on their way to kill the male Dragon in London. London is due south of Manchester. Why then did they head in the complete opposite direction to Northumberland?
Plot hole: When Eldon checks out the address Van Meter gave him he finds where Orchard and Sidwell are living. All well and good, except: A) The utilities bill is in the names of Orchard and Sidwell, who are known wanted felons in L.A. and B) even more implausibly, the bill is in BOTH their names.
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: Since when do highly trained, professional police/SWAT operatives run lemming-like at perpetrators in an armoured assault vehicle with an M-60 in it? This wouldn't happen.
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: When Delila finds out who Jimmy really is, she takes his tuxedo and is apprehended by the bad guys. She then turns on her homing device on her necklace. The office says it will take 20 minutes to get to her. From that statement to when the CSA finally arrives, Jimmy has time to go to Devlin's, write him a letter, discover water striders, find his suit, and get back to Delila and fight the bad guys. THEN CSA shows up. The timing is really off.
Plot hole: When the umbrella ops first get onto the train, rain has to power it up. There were plugs disconnected, and you see a hole in the fence as she shines a flashlight on it. It can't be anything infected because they didn't power down the red queen yet, and release the bioweapons. The red queen isn't physical, just controls systems. And with none of the zombies, or other infected loose yet, what else could have unplugged it? Spence was knocked out on the train, this seems to be a plot hole. (00:02:00 - 00:20:10)
Plot hole: The drug dealer guy gives Arnie a hood to wear so as to not see where they were going. When he puts it on we can see his face through it like a streched sock or something, meaning he could still see.
Plot hole: Shortly before the penultimate fight between Feathers and UB, Smart Brother comments that UB has a few seconds before the reactor goes. Yet, no matter how loosely SB's words are interpreted, the whole sequence from when he said that to when it blew lasted longer than "a few seconds".
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: When they were on the boat fighting, the girl that got shot in the head would be moving instead of just lying there.
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).
Suggested correction: I thought that this was a mistake as soon as I saw it on screen, but reconsidered. It's perfectly possible that there was some, probably human caused, delay in updating the security system. After all, there wasn't a rush to do it since they already had the chief on ice. Maybe the sleep jail was still on a legacy system without automatic updating. Just assuming that in the near future that all systems are all perfectly integrated and instantaneous does not validate this as a mistake.
