Factual error: When Brian fires his pistol in the air, eventually killing the Super Devil, we hear six gunshots, each followed the distinct clink of the ejected cartridge hitting the ground. Trouble is, Brian is firing a revolver, which does not eject the cartridge after the bullet is fired. Only automatics do that.
Continuity mistake: When the flag team first walks out to the field, they are all in a straight line. Next time they are in two seperate lines with Meg at the head. Also, the girl with the head brace moves to the front when she is seen in the back. There is not enough time for them to move into the lines.
