Phantasm III: Lord of the Dead

In this, the final episode of the horror trilogy, we re-visit Mike and Reggie fifteen years after the events of the first film. The orphaned brothers have come together once again to battle the forces of evil. As they travel through various alternate dimensions in search of the infamous Tall Man, the two must take care not to cross the path of a floating, three-pronged sphere that could turn their brains into so much yogurt.
