Revealing mistake: When father and son are parasailing, in the close-ups (an obvious green screen effect) the clouds never change shape, note the small one on the left, revealing it's a still image.
Continuity mistake: After a guy shoots at an abandoned jet, the objective lens still shows the plane undamaged, as it was before he fired.
Continuity mistake: When Sattler, Mark and Grant are at home, the mug in Sattler's hands suddenly disappears.
Continuity mistake: When the boat carrying the parasailing guys is about to crash, the sky keeps swapping between cloudy and sunny depending on the shot.
Continuity mistake: When the front of the plane is ripped off, there are 2 people sat in the pilot and co pilot seat. As the camera changes one of them has disappeared from the seat and is further back in the plane. (00:24:50)
Continuity mistake: When the spinosaurus is chasing Grant and the kid and hits the fence the sun changes between shots.
Other mistake: When the Navy picks up the survivors, the person on the radio says that they have 6 souls on board. They only picked up 5 people.
Suggested correction: The 5 he picked up and including himself.
This correction really makes no sense. The pilot says "6 souls on board" but there's at least 9 on board. Grant, Paul, Amanda, and Eric, were picked up. Billy was already on board. Then there was the Man in Suit, 2 pilots, and a what appears to be an attending medical officer.
Other mistake: When the plane drops out of the tree with the tail going down and all the people in the tail, it crashes and the metal actually crushes upward. There is no way that those people could walk out of that plane uninjured.
Factual error: When they find the camcorder and discover the battery is dead, Udesky takes the batteries from his Maglite, and they magically work in the camcorder.
