Justice League: The Flashpoint Paradox picture

Plot hole: After Reverse Flash saves Lois Lane and kills all the Amazons that were attacking her, he disappears, just before a group of resistance fighters shows up. They know that they didn't take out any of the Amazons, it's obvious that Lois didn't kill them, yet the resistance members show no concern as to who was responsible. The war involves three separate groups, the resistance, the Amazons and the Atlanteans, each of whom is equally hostile to the other two. As such, the resistance cannot assume that whoever killed the Amazons must be an ally and let their guard down, as it could easily have been an Atlantean force, who would make no distinction between the Amazons and the resistance and would attack them on sight. An experienced resistance team would not be so casual about the situation. (00:40:50)

Pokémon Detective Pikachu picture

Plot hole: After Pikachu and Mewtwo begin falling down, Tim is suddenly on the ground in a matter of seconds, with little to no time to arrive there. There are multiple stairs, and he does not have any Pokémon to help him get down. He couldn't have gotten to the ground that fast.

The Tomorrow War picture

Plot hole: Dan returns from the future with a vial of toxins with him that can kill all the white spikes. He tells somebody to start mass-producing it but this information is not spread across governments or even made public, but it is the one thing they have that can prevent humanity's extinction and making people aware of that will stop the rioting.

Oblivion picture

Plot hole: According to the flight recording, Odyssey was on an uncontrolled pull towards the Tet as Jack says, "We're not getting away from this thing." So even if Jack jettisoned the sleep module where Julia was in, the module should not be able to get away as the whole ship is being pulled towards the Tet.

Suggested correction: It can be assumed that the jettisoned module has enough "jettison power" to force it away from the command pod. And in turn that force would move the pod further towards the Tet. It's reasonable to assume the Tet couldn't pull the module that was moving away, under dramatic force, and to which it didn't have line of sight (which was blocked by the pod).

The Cave picture

Plot hole: Tyler jumps into the water, then grabs his mask and puts it on and begins swimming, but he fails to clear his mask by blowing the water out of it. Without clearing it, he wouldn't have been able to see a thing.

D.A.R.Y.L. picture

Plot hole: If the government guys could see Daryl in the cockpit, they should have known they could finish him off. If they launched a missile, he would either be hit by it or cook himself himself trying to outrun or outclimb it.

The Lost World picture

Plot hole: In the arial shot of the plateau, it's obvious its just a mesa. It's not at all large enough to support such big animals like those dinosaurs, who would have to eat great amounts of food. All small animals would be hunted into extinction, and all of the trees would have been cleared out long ago. Plus, there would be no place for the dinosaurs to hide, so the team should have seen the monsters right away.

Mimic picture

Plot hole: Susan theorises that the insects have evolved to resemble people because of predatory pressure. However, for this to be true people must have been killing them - apart from the handful of 'moles and junkies' (who were the prey, not the killers) this film shows the first contact between humans and the evolved 'Judas bug'.

Quatermass and the Pit picture

Plot hole: When Quatermass is being admonished by the senior minister for talking to the press, Breen gives his own theory to explain the presence of the spaceship: He says that it was used a propaganda weapon in 1944 and that the figures inside were made up of scraps old skin and bone, why was he unable to explain how the hull of the spaceship was heat resistant up to 3,000 degrees and harder than diamond?

Hobgoblins picture

Plot hole: After Dennis (the first guard assistant) gets killed, the vault is open for several minutes before the old guard arrives. The hobgoblins, however, do not run for their freedom, but patiently wait until the hero, Kevin, comes in a later scene and opens the door. Then they escape as quickly as they can.

Species II picture

Plot hole: The rape scene in the parking lot... there is no one around for THAT long? But wait, once the detectives come in the scene two people are walking in the background with a shopping cart - they must have seen something!

Mars Attacks! picture

Plot hole: If the president thinks it's so important that the Martians comes to the Congress to present their excuses, why didn't they bring the translating machine? (00:52:35)

Suggested correction: Because, as has been demonstrated, the "translating" machine is about as much use as t*ts on a tomcat.

Plot hole: When Bethlehem is shot you can see the bullet come through his chest. But why doesn't Ford get hit by the bullet? Ford is standing right in front of him. (02:39:55)

Demolition Man picture

Plot hole: When Spartan jumps through the window in the excavation scene of the museum, he crashes into a room with bottles of drink on the shelves. Surely this room too would have been filled in and the window smashed during the earthquake, and the museum wouldn't have bothered to excavate it as it can't be seen from above due to the blanked out window. So what is that room doing there? (00:49:20)

Upvote valid corrections to help move entries into the corrections section.

Suggested correction: It is not an excavation. It is only made to appear like an excavation for the museum; it is all decor to display the 20th century items like the car.

Plot hole: In the scene where Richard Gere is looking at his reflection in the motel bathroom mirror, he imagines smashing his face into the mirror. When the phone rings, breaking his hallucination, he still has blood on his hands but it is never addressed.

Paul picture

Plot hole: The huge explosion that rips through Tara's house isn't very likely. She only left the stove on for a short while, and if there was really a massive concentration of gas as depicted by the explosion, the Agent who fired the shot that triggered it should have collapsed from inhaling so much gas.

Plot hole: When Debbie and Mike are in the pink cocoon room of the circus tent Mike yells, 'Joe Lombardo.' However, Joe Lombardo doesn't die until at least 4 scenes later in the movie, when a Killer Klown edges him off the road and over a cliff.
