When Clyde is working on the bus, the fan blade is visible in the shroud, yet when the engine is cranking, and sound effects indicate it is turning over, the fan blade does not move.

When Tricia expires in the care of Doc, her eyelids move slightly as the blanket is pulled over her.

There are several scenes where there is considerable snow on the ground and then no snow and then snow again when it is supposedly the same day. During the scene where the characters are trapped in the bus there are alternating shots of snow falling and a clear night, even a shot of a full moon, within minutes of each other.
