Revealing mistake: In the swimming pool scene, when David is sitting at the bottom of the pool, you can clearly see a scab on one of his knees. (00:43:00)
Audio problem: After the aeroplane crashed, a dinosaur stepped over it and the windows shattered making the typical sound of made-of-glass things when broken. They are made of plexiglass (a sort of fibrous plastic).
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?
Continuity mistake: In the beginning scenes, where Milo Thatch is practising his proposal, he slides over (face forward, chest against the board) a chalk drawing of a map detailing the location of Atlantis. When he realises he wiped off the drawing, and sees it on his clothes, he stands in front of the blank part of the chalkboard, "filling in" the space with the map that rubbed off on his shirt - the only problem is, that the image should have rubbed off backwards as he was facing the board when it transferred to his clothes. He could not simply stand in the place of the missing map face forward and have it read properly.
Continuity mistake: During the fight with Gabe and Yulaw, Yulaw does a powerful move of lunging forward and smashing Gabe with both his fists, sending him flying into a green metal box that crumbles from the impact. Gabe then falls to the floor, close to the box. The shot changes to Yulaw thinking he has victory, then back to Gabe. Gabe is now noticeably further from the green box, and his arms and legs are in different positions. (01:08:40)
Continuity mistake: When Juni handcuffs the metal box to his wrist, it switches back forth from his right wrist to his left over and over again. (00:35:05)
Continuity mistake: During the scene in the mall when the girl is in the dressing room, she keeps putting on more layers of clothing. But as they are shooting different shots she will have a hot pink shirt on, then it is back on the hanger, and then back on again. It switches back and forth many times. (01:00:50)
Audio problem: On the first level of the video game, after Velma brings up what she remembers what Eric said about the Scooby snacks in the game, you hear Daphne talking but you see Velma's lips moving. (00:01:00)
Factual error: In the begining at the bridge ceremony, the band plays Manhattan Beach by John Philip Sousa. However, Manhattan Beach was composed in 1893. (00:00:50)
Other mistake: When Prot visits the doctor's house, he thanks the wife and the camera is zoomed into his sunglasses. The reflection of his glasses shows the doctor looking at him, but the doctor is standing behind him. (00:53:40)
Visible crew/equipment: When Donnie and his Dad are in the car, talking, prior to nearly hitting Grandma Death, in the window behind Donnie's Dad is the reflection of a vehicle which says "Darko" clearly on it. There's also the reflection of a clapperboard on the backseat. (00:21:00)
Continuity mistake: When the panel of doctors are being queried by Aames, for the second time of the loop of this interview, the black box containing the mask can clearly be seen in the bottom right hand corner on the desk when the camera swings to the main doctor. When the camera pans back again, it is gone, and it is only after this that the assistant brings in the box.
Continuity mistake: Nick's necklace is a string looped through a ring, but sometimes the string makes only one pass through the ring and sometimes two.
Revealing mistake: When Kay-Em kicks Jason in the face during the fight sequence, you can see Kane Hodder's goatee. (01:03:40)
Continuity mistake: The grandfather, father, and son all have VERY blue eyes, but in the flashback scenes, the actor playing the grandfather as a young man has very dark eyes.
Continuity mistake: When TJ jumps in the dumpster at the school to hide from the guys in suits, he sees two guys and another who's dressed up like Principal Prickly in his normal shabby suit, but then a second later when he takes off his Prickly mask he's in a black suit.
Continuity mistake: When Remy falls through the barricade she is wearing a G-string, but when she strips down to mix up the scent she is wearing different underwear.
Continuity mistake: Right after Aki saves Gray and turns around to pick up the canister containing the plant off a table there is no table or ledge. If you watch the movie with the commentary one of the members involved with the movie says that it is floating on nothing. (00:16:50)
Revealing mistake: Have a look at the shot of the rear part of the train exploding as the locomotive pulls away from it. If there was ever a more obvious model shot, with cheesy, jerky bouncing toy trains and Action Man (TM) dolls, then I haven't seen it.
Continuity mistake: In the scene where Rock is trying to destroy Tima and the factory, the side parting in his hair frequently changes sides.
