Continuity mistake: In the film the Eye Creatures have landed their spaceship in a field during the night and the Army has been called in to survey the spaceship. A soldier gets on top of the space ship and starts using a welding unit to try and open it and it's bright and clear out. The temperature of the welding ignites a fuse on the spaceship which causes the ship to explode. When the scene shows the spaceship blowing up it's now pitch black outside.
Visible crew/equipment: Throughout the movie, if you watch closely you can see the zippers on the backs of the Eye Creatures' costumes pretty easily.
Visible crew/equipment: Near the end of the film the Eye Creatures are seen coming out of the woods. When you watch the scene, one of the people playing an Eye Creature is shown walking with nothing but the Eye Creature head appliance, black clothes and sneakers.
