Revealing mistake: When the plane first lands at Bangor airport, the words 'American Pride' on the plane are reversed, like they are reflected in a mirror in one shot as its wheels hits the runway. (00:50:55)
Revealing mistake: In the scene when they all have just arrived at Bangor when Bob Jenkins compares his watch with a clock (he looks if there are batteries inside) I'm not sure, but I guess one battery is reversed so that the clock is stopped. (01:01:45)
Revealing mistake: When everyone goes up to the second floor on the escalator, behind them outside through the glass doors you can see people walking about. (01:09:10)
Suggested correction: I have rewatched this scene and saw no people.
Revealing mistake: When the Langoliers make a hole in the ground to stop the passengers from leaving, Brian turns the plane around so that the plane can take off from a different part of the runway. In the shot of the plane turning around, tyre marks can be seen on the ground, presumably from previous takes. (02:15:32)
Suggested correction: This was filmed in and around Bangor International Airport. Of course, there will be tyre marks.
Revealing mistake: Near the end, as they approach LAX, the woman says there is nobody on the ground, that it's just the same as Bangor, but actually you can see a few cars moving on the ground.
Revealing mistake: Just before they land at Bangor airport we have two or three shots behind the pilot. I am not a hair dresser but I believe that you can see the difference between the real pilot's hair and the actor's.
