Plot hole: Anubis Warriors can only be killed by being beheaded. But during the final battle, you see several are killed by simply being stabbed.
Plot hole: The "video history" of the crashed USAF ship makes it very clear that the planet is uninhabited when they "landed". I can understand how a race of apes develops - they had a bunch of them on board. I can understand how a race of humans develops - they are descendants of the original crew. What I don't understand is...where the heck did all the horses come from?
Suggested correction: Humans refer to parts of their own planet as uninhabited even though they are crawling with animals - vast areas of the Arctic are "uninhabited" even though polar bears and seals are found there. Were we to find a planet with nothing but primitive horses on it, we would label it as uninhabited. Apes and humans came from the crashed spaceship, horses were always there.
Which still makes no sense whatsoever.
I agree with you Charles. Horses are native to Earth but, the Oberon lands on a planet light years from Earth so it's a big plot hole how horses from one planet could end up on another when the planet was not only uninhabited but, the Oberon was believed to be lost.
Again, the Oberon was a massive space station, genetically experimenting with many earthly lifeforms, including horses, apparently. The time/space-rift was very near Earth (Mark Wahlberg made the journey in about 25 seconds at the end of the film. Not years but seconds). The implication is that the Oberon passed through the rift, and much of the crew survived to continue their genetic research on what later became the Ape Planet. So, the Oberon initially arrived on a barren planet and introduced all of the biological and botanical species, including apes, horses, and everything else.
Suggested correction: According to the backstory, the space station Oberon was dedicated to genetic modification sciences. They were actually experimenting with animal genes in the safety of space (which kind of makes sense). Given that the Oberon was a truly gigantic space station, it's not too much of a speculation that they were experimenting on many different types of animals (not just apes). When the Oberon crashed on Ashlar, half its crew was killed, but half survived with a number of ship's systems still functional, and they continued their genetic research, possibly producing a number of Earthly species on the otherwise uninhabited planet.
I think this should've been posted as a question, rather than a plot hole.
That's just a wild guess. There hasn't been a single mention of horses on board the Oberon. Even if there were, why only horses?
Wild guess? The Oberon was experimenting in genetic modification, which implies a broad range of research...and not just on great apes. The Oberon was gigantic enough to be an Ark.
So where are all the other animals?
Exactly. Where are the birds, lions, lizards, etc?
Plot hole: Where do the flyers come from that are in the bags that are carried out of the vault and into the van? Danny and Linus couldn't have taken them down there and there is no room with the Chinese man. They are carried out to the van before the SWAT team appears, which means they'd have to have been in the vault to start with? In the commentary by Steven Soderbergh he acknowledges that there's no explanation. (01:35:05)
Plot hole: Spoiler: At the end of the film we learn that the girl is the wild animal, having been saved by the same doctor. Yet at the restaurant she is wearing a bare back dress and does not have the giant X-like scar on her back, like he has or the model has, who the doctor marries at the end.
Plot hole: The spinosaurus manages to smash through a metal reinforced wall designed to stop dinosaurs getting past it without too much effort, yet it can't get through a wooden gate secured by some metal bars. It makes no sense.
Suggested correction: The Spinosaurus used its full body force to smash the fence. The gate, being a smaller target, was too small for the Spinosaurus to use its full body force.
Plot hole: How could the police miss finding Cybil in the trunk of Michael Zane's car when it was in an impound lot? They would have definitely searched the car if he was found in violation of a federal offence (for carrying the weapons). Even if they didn't do a search, they would certainly have heard the sounds that Cybil would have made from being locked in the trunk.
Plot hole: When Carlos (Bill Maher) is explaining to Michael what was a valid roll he says that the redhead rubbed the dice on her chest for good luck and threw them. However she immediately threw the dice when Michael handed them to her. She only rubbed them on her chest and gave them back to Michael on a prior roll.
Plot hole: When the Grundel explodes near the end, Rowan looks out the window to see Uber Jason floating towards the rescue shuttle, only to be grabbed by Brodski who happens to fly sideways at a high rate of speed. Now provided it's feasible that Uber Jason can survive an immense explosion, how Brodski not only survived the explosion but managed to wind up away from the spaceship and far enough off to the right so as to catch Jason in mid-space is beyond me. (01:22:15)
Plot hole: Stuart establishes that there is only one of you and that when you travel through time you can repeat things, but it will be you and not your double that does it. But, at the end, when the Duke is going up the stairs and the uncle says "Where have you been...", the Duke is wearing the same clothes as the first time. Yet we see that he goes directly from the time portal to his house in the ballroom raiment of the later scene. Where did the old clothes come from?
Plot hole: On the doors inside the white dome, and on the elevator door, it is marked "Vapor Lock." This is impossible due to the mine shaft opening. It can't be vapor locked when there's an opening. (00:35:00)
Plot hole: When the security guards enter the cage housing the blown safe there are no traces of the water used to break the safe - not even on the (dry) floor. This happens only minutes after the explosion sent the safe door and gallons of water across the cage.
Plot hole: When Marty lies on the conveyer belt on the way to the stone crusher he tries to wiggle off the belt. The little he seems to be able to move is not justified by the way his hands and feet are tied up. (01:08:30)
Plot hole: When the aliens kidnap the adults, the kids are left behind. But all the kids seen are around 11 and younger. Where are the teenagers or young adults? None of them are during the celebration scene nor in the arena on the alien planet.
