Factual error: In scenes apparently in Japan, all the cars drive on the right side of the road. In actuality, the Japanese drive on the left side of the road.
Character mistake: When Sam pushes Freddie off the plane, his mother puts on the parachute and jumps out as well. She is in such a hurry, that she doesn't buckle the straps across the front. In real life, as soon as the parachute is deployed, the resistance would cause the parachute to come off and she would likely fall to her death.
