A nameless member

Trivia: There are three different hockey masks used either in this film or its advertisements. The first is the one that the Jason impostor (Roy) wears. It has two blue triangles below the eyes. The second is the one the real Jason wears when Tommy sees him in the hospital room at the end, with the red triangles. The third is featured on the poster. It has an un-holy amount of breathing holes on it. (01:23:00 - 01:27:10)

Continuity mistake: Toward the end, when James Belushi swerves to miss his dog in the middle of the street he crashes his car into a parked car and then roll to a stop. Notice before the camera cuts to a frontal shot of the wrecked car, that there is a huge spider crack in the windshield, as if James hit it with his head. This huge spider crack then disappears once the camera cuts to the frontal shot and the windshield is in perfect shape. (01:33:45)
