Corrected entry: The scene where he just got a fire going and is throwing logs on the fire on the beach, notice how calm the water is. Every other shot of the water has huge waves just to leave the island. Why didn't he just leave from the beach he had the fire on?
Corrected entry: In the scene where Chuck is floating in the water on the raft you can see that the raft is yellow. When he gets on land and puts the raft up by the trees it is orange. Throughout the whole movie you can see that the raft changes from yellow to orange.
Corrected entry: Chuck's plane was supposed to have gone down in 1995 and he was on the island for just under 4 years, but when he is talking to Kelly in her house about the Tennessee Titans, she says they "were in the Super Bowl last year." Even if the crash happened in December of '95, he'd have been home by the end of '99, a minimum of a few months prior to the Titans Super Bowl appearance (which was actually in January of 2000 - Super Bowl XXIV).
Corrected entry: After the plane crash, when Tom Hanks is in the raft, he falls asleep and awakes only when the raft hits a rock on the island and a section of the raft deflates. How did the raft get over all those gigantic waves on the reef without capsizing? (Especially with the high waves that would occur after a storm.) Did Tom sleep right through it all?
Corrected entry: He is on a flight going to the Far East. All the packages have domestic airbills. If they were on international airbills it would not be necessary for him to open the package to see what was inside, a description of the contents would be clearly visible on the airbill.
Corrected entry: When Tom is taking a leak on the beach at night he turns away from the beach and toward the camera. The fake ship's light is viewable in the distance. Tom is squinting badly at that point and there is a large glare on his shoulder, indicating the scene was shot during bright sunlight. Even in a bright moon the squint is unlikely.
Corrected entry: In the scene where Chuck is finally rescued by the ship and he is holding his arm out towards the ship, if you look under the raft it looks like you can see the lines on the bottom of a swimming pool.. considering he is in the ocean the water doesn't really look that deep.
Corrected entry: When Chuck is going down with the plane his life boat has a small reddish bag attached. This gets attached to some metal piece and starts to pull him further underwater until it snaps off. Once on the island, he starts to drag the life boat towards the trees. As he walks further up you can see the little red bag being dragged behind the life boat.
