Continuity mistake: As Brian lands the plane down to Bangor, his headset is on in a frontal shot, but in a reverse shot it isn't. (00:47:05)
Visible crew/equipment: When it shows Toomey's father sitting down with a newspaper, as he gets up to shout at Craig, a boom mike is visible, above him. (01:06:35)
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)
Continuity mistake: After Albert knocks Craig Toomey unconscious with the toaster, as it shows different angles of him laying on the floor, his tie is alternately hanging out/tucked into his suit. (01:48:55)
Continuity mistake: When the airport manager tells Brian his ex-wife died in a fire, they exit gate 54, but in the next shot, as they continue to walk down the terminal, it shows them exiting from gate 51. (00:05:00)
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)
Factual error: When initially investigating the missing people and the condition of the airplane, Brian looks at a screen that gives the airplane's transponder code (or "squawk") as 7777. An airliner would never be squawking that code, since this particular code is reserved for military interceptor operations.
Other mistake: In the scene where they are 1st landing at Bangor it is known that there is no electricity at the airport. If you look closely during the landing you will see that the runway lights are on. (00:50:40)
Continuity mistake: The holes which the Langoliers make near the aeroplane, when they chase after Criag Toomy, change position, size, shape, move closer to the plane and then finally vanish. (02:13:30)
Continuity mistake: Albert knocks Toomey out with a toaster. You can see during several subsequent shots that there is only a small amount of blood on Toomey's forehead and none at all on his face. Toomey lies there unconscious for a while, without changing position, and when he wakes up, suddenly his whole face is cut up and bloody. (01:54:00 - 01:59:05)
Continuity mistake: After Nick lets go of Toomey's nose, Toomey is shown placing his left hand over his nose. When the shot cuts, it is now his right hand placed over his nose. (00:17:00)
Continuity mistake: When the Langoliers begin eating Toomey, Nick grabs hold of Laurel while he closes the door. In one shot, Laurel's hair is under Nick's arm leaving her left shoulder exposed. But in the next shot as the door starts to close, Laurel's left shoulder is suddenly covered by her hair. (02:14:54)
Continuity mistake: When Brian is about to fly back through the time rift, there is a mixture of blue and orange lighting coming from the rift that is cast on him and the wall behind him. When Nick rushes into the cockpit to tell him to turn back, in the close-up of Brian, the wall behind has blue light on it. When the shot cuts to have Nick and Brian in the frame, the wall now has orange light on it. (02:33:43)
Continuity mistake: When Nick sits back in the passenger seat after Brian turns away from the time rift, he is holding onto his left arm after banging it. When he sits down, his left hand is placed over his right arm. When the shot cuts, his left hand is suddenly raised upward slightly. (02:34:58)
Visible crew/equipment: When everyone realises Toomey is on the runway and about to run past, Bethany, Rudy, Nick, Brian and Laurel are shown going outside to stand on the top of the airstair to see him. Just as Brian steps out of the plane, part of the boom mic can be seen entering the frame to the left of the shot. (02:09:36)
Continuity mistake: When the Langoliers bite off Toomey's leg, he falls to the ground and his tie can be seen falling over his right shoulder. When the camera cuts to an angle behind him, the tie cannot be seen over his shoulder. A couple of shots after that, the tie suddenly over his chest. (02:14:35)
Continuity mistake: When Toomey is begging his father to make the Langoliers go away before they eat him, he has his hands raised in front of his face. There is then a close-up of his mouth, and we can see to the left of shot, his hand grabbing onto the side of his head. (02:14:48)
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.
Continuity mistake: When everyone begins walking to Bangor Airport, in the wide shot Brian is behind the rest of the group. When the shot cuts, he is suddenly ahead of Gaffney. (00:58:27)
Continuity mistake: When preparing to fuel up the plane, Bethany bends down and opens the fuel tank. Once she stands back up, her back is hunched forward slightly, her right arm is in a reaching position and her leg is bent. When the shot cuts, she is standing fully upright, her arm is no longer reaching downward and her leg is unbent. (02:01:10)
