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?

Continuity: When Thade takes the weapon from Leo the weapon is a futuristic laser type gun. When Thade is firing the weapon after being locked in the command centre, the gun is a stainless steel Beretta brigadier model.

Continuity: When Leo is carrying Ari across the river she scratches him on the neck. For the rest of the movie the scratch changes sides and sometimes disappears completely.

Revealing: After the trained chimp is shot and is crawling into the cage, they show a shot of an ape turning around. You don't even have to look hard to see it but there's a two inch strip all the way down his face with no makeup. Clear as day.

Continuity: When they cross the river and arrive at the other side, they are all dry. Mark Wahlberg was in the water up to his neck and sometimes higher yet he seems to be completely dry.

Continuity: After the big battle between the humans and the apes and everyone has made nice, we see Ari crying over Krull's body partially covered in sand. Then she covers his face. The camera cuts back and you can see his face clearly.

Continuity: After the group cross the river, they set up camp and make fires.  They are in the middle of the desert and there are no trees as far as the horizon. Where did they get the firewood?

Continuity: When the hero and his group comes out of the ship wreck and you get a shot from some distance back at the ship, look to the far right and you will see a road (sloping down towards the ship) with clear tire tracks on it. Whose car might that be?

Continuity: When the monkey accelerates his pod, it shows his hand pulling the silver levers backwards. Shortly after, when Mark Wahlberg accelerates after the monkey he pushes the levers forwards.

Continuity: When the humans are about to be branded the branding iron is in the fire heating up. It stays glowing red hot the whole time Leo is threatening Ari, at least 5 minutes.

Revealing: When one of the people on Mark Wahlberg's team runs to a huge ape after an ape has escaped Paul Giamatti his hand gets cramped by the big ape. You can see a slight grin on his face, so you know he's not really hurt.

Revealing: The humans on the planet live a prehistoric existence with little technology, however, they seem to be remarkably good at making foundation garments. Estella Warren spends most of the movie running around in nothing but an animal skin and yet her considerable assets are always held firmly in place.

Continuity: In the scene where Leo dives in the pond, where his pod crashed, to get his bag, he dives in and it is dark and dingy, yet when you see an underwater shot the water is a clear blue/green colour and you can see the sun (or some form of light) shinning through the water, yet when he comes out there is no light and it is dingy again.

Continuity: When Leo and his group of rebel apes are starting to ride their horses across the river, the Bonham-Carter character falls off her horse and he swims across the river with her on his back. The other apes can't follow because they're afraid of water. So they arrive horseless. However, when they get across the river, suddenly everybody has horses.

Continuity: When the pod carrying the Mark Wahlberg character crashes into the lake, there is a human figure on the opposite side of the lake to the camera position, slowly walking right to left.  The pod is travelling left to right.  The figure is on the left-hand side of the screen, in the trees, but clearly visible. It can't be one of the humans that Wahlberg bumps into a few minutes later, as it's not running due to being pursued by apes, and its not moving away from the oncoming spacecraft (if monkeys scare these guys, then a crash-landing ball of fire would surely freak them out).

Continuity: In the scene where all the humans are about to be branded, one of the humans is removed from the cage and the funny old ape just pushes the cage door shut, not locking it.   A few moments later the camera pans round and you see that the cage is now bolted.

Other: When the group returns to the lake where Leo crashed, as he is underwater leaving the pod with his pack, he has it in his left hand. The next scene he grabs Estella Warren's hand with his left. The pack is gone. As they swim up, if you watch it frame by frame, the pack instantly appears back around his left forearm before they surface.

Continuity: When Leo gets into the pod to try to catch the chimp's pod, he puts on his helmet. Look away, look back, and he's all snapped and buckled in, which would have taken several minutes at least.

Continuity: In the scene where the humans are being loaded up. We see Leo (Mark Wahlberg) lying on the ground starting to sit up. Then the camera cuts to Thade (Tim Roth) and then back to Leo who is again just starting to sit up, surprised to see talking apes.

Continuity: At the beginning of the movie Leo's uniform is clean and white when he enters the pod. Subsequently the pod enters the vortex, enters the Planet's atmosphere and then splashes down in a tropical pond. As Leo leaves the sunken pond, his white and pristine uniform has somehow developed 1000 tatters although the only stress it has been subjected to is the water on the planet. What a bleak future awaits us all if seams in the future are water soluble...
