Corrected entry: At the Russian FedEx Office, Hanks orders everyone to get all the boxes into the "big truck". Actually, as he is working for FedEx, he would know the term is "shuttle".
Corrected entry: In the plane crash scene, Chuck is underwater and activates the self-inflatable life raft. The raft fills with air, and he is propelled to the surface. But a self-inflatable raft uses internal vacuum to pull outside air in. Underwater, it would fill with water. The red thing is not some air container either; it's likely a package of survival goods and is only attached by a tether.
Corrected entry: Near the end of the movie, Kelly says that Chuck's island was about 600 miles south of the Cook Islands, but there isn't anything south of the Cook Islands besides Antarctica.
Corrected entry: Why is the package that Chuck never opens on a flight from the U.S. to the far east, if it's meant to be delivered to Texas?
Corrected entry: As the plane hits the water, Chuck falls backward, toward the rear of the plane. This violates the concept of inertia. He actually would have continued traveling forward toward the incoming water.
Corrected entry: When Chuck tries to get away with his liferaft, it sinks, and the coral pierces his upper leg. Though this is just a fleshwound, it's pretty nasty. He has no medical equipment whatsoever. But when he lies on the raft four years later, when his legs are visible there is not the slightest scar where he was wounded.
Corrected entry: Assuming Tom Hanks was going from Memphis to Kaula Lumpur (which I don't believe was actually discussed), the airplane as seen from the inside is either an MD-11 or possibly a DC10 with a glass cockpit. If so, the that route is beyond the range (9768 NM) of either airplane. It is even further to Sydney, Australia so I don't think that is very likely to have happened without a fuel stop, that didn't happen either.
Corrected entry: A FedEx car is shown clamped next to the Spassky Gate on the Red Square. Cars are not allowed to be parked there at all as a security measure - they'd be towed away, not clamped.
Corrected entry: All airliners are pressurized in flight to approximately 8000ft, and any item inflated at ground level would have higher pressure, thus when the aircraft is pressurized in flight the difference in the lower cabin pressure and the higher pressure in the inflated item would risk it exploding, for this reason it is a requirement to deflate all items such as footballs and bike tyres before being placed on the flight. For this reason Wilson the football should not have been put on this flight.
Corrected entry: When Chuck spears his first crab he holds it up and it shows 6 little legs moving. Chuck then grabs off a leg to eat and it has a huge claw on it. The one he speared did not have claws.
Corrected entry: When Noland is casually urinating into the ocean late one night we see a light on the horizon. It can only be from a passing ship. Noland doesn't react at all, and it is directly in his line of sight. He couldn't miss it.
Corrected entry: The orientation of the plane is all wrong. Hanks goes into the bathroom, which is located aft of a crew door, and against the front of the cargo area. The bathroom on all the wide body aircraft (Airbuses, DC-10, MD-11) is located between the cockpit and the jumpseat area.
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: It is clear when Tom Hanks is on top of the island, and when he sees the dead body, and also when he walks around the island, that the fringing reef does not extend all the way round the island. There is therefore no need to launch the raft into the breaking waves, it would be much easier to launch the raft at a place on the island where there are no breakers to contend with. (You can also see this in an aerial shot of the island on page 84 of the book "Nomads of the Wind").
Corrected entry: In the scenes 4 years after Chuck has been on the island, we see he has grown his hair out and his beard is very long. What is out of place is his mustache is remarkably well-groomed. Whiskers don't grow evenly, and unless he had some scissors or something else to trim with, it's very unlikely that his mustache would be so evenly distributed around his mouth.
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: 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?
