Continuity mistake: After Jason tells Ben he is sorry for yelling at him, Ben turns his head and lays it down to go to sleep. But next, his head is up and facing Jason as though he has not turned away. Ben turns and puts his head down a second time. (00:41:33)
Continuity mistake: There isn't a white notepad on top of the smaller green present (with the gold present missing), but there is when Ben pulls Jason's notepad out of the storage compartment. Even though Ben is facing Sam and has Jason's notepad in his hands, the white notepad behind him is angled differently at least twice. (00:17:15 - 00:17:37)
Continuity mistake: Ben places a flashlight on top of the smaller gold Christmas present (which recently re-appears), but the flashlight and gold present disappear when his arms/upper body come back out of the storage compartment. The large green present is angled away from the others but touches the larger gold present. When the top gold present goes missing, the green present is parallel to and touches the larger gold present. (00:16:29)
Continuity mistake: The wrapped Christmas presents set near the airplane's tail are stacked differently in the before and after views of Ben's arms in the storage compartment. The gold package that is on top is missing and the larger green package on the ground is angled away from the others. Later, the green package is aligned with and touching the lower gold package. (00:16:39)
Other mistake: In the distant view, there is a field but no trees close to the pilot's side of the plane right after Jason lands, but there is a row of pine trees nearby when Sam and Ben are standing on the opposite side of the plane. There is also a wider view of the field (with no trees close to the plane) when Jason, Sam, and Ben start walking. (00:11:27 - 00:28:27)
Revealing mistake: In the underwater view of the fish, the ice hole is almost perfectly round and the ice appears to be quite thin - nowhere near the several inches Jason and Ben have to chip away to reach water. (00:33:55)
