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?
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.
Plot hole: When Martin decides to antagonize David by eating spinach, he eats it from his plate. When they both eat the spinach frantically, they each eat out of a large bowl. Where did the second large bowl come from, and why would there even be a second one if they only need enough for three people? (00:34:55)Matty Blast
Plot hole: The legend of the black knight (in this film) is that he can breathe dragon's fire. Jamal somehow rigs up his aerosol spray-can inside his helmet to shoot out the flames. However, there are three problems with this: one, how did it fit in the helmet? Two, how did he activate the spraying mechanism without his hands? And three, how did he even ignite the spray?

Plot hole: There is no way that 'coast of Iceland' could ever have been mistranslated as 'coast of Ireland'. For this to have happened, they would have had to have thought that the 'C' rune was an 'R' rune, but they had already deciphered the word 'coast', so they knew what the 'C' rune was. The 'O's are the same rune and the 'A's are the same rune, plus there is one rune for every letter, so it it's a direct letter-by-letter translation.Blibbetyblip
Plot hole: When her father is taking the "shortcut" he somehow doesn't need to shift gears even though he has a manual transmission. At the speed he was at he should be in at least 2nd gear.
Plot hole: If the ancient civilization wanted to stop people from ever using the power of the triangle again, why didn't they just destroy the triangle right then and there instead of splitting it in two and hiding the pieces? It would make sure that no one would ever get the power of the triangle and is easier than going to ends of the earth and creating all sorts of traps and challenges.Piemanmoo
Plot hole: When Jimmy is in his little rocketship launching his toaster satellite into space, the morning newspaper that his dad is reading already has the photo of the rocketship on the front page as a UFO. But the military jets were the first ones to spot the rocketship, the newspaper couldn't have gotten the story and printed it out that quick.
