Scary images for a PG-rated film. Children are in peril, often at the hands of magical creatures: Dementors (black-robed floating beings that suck the happiness out of people) attack Harry and others, making Harry hear the sound of his mother dying as he passes out; they almost administer "the kiss of death," extracting a character's soul through his mouth. A hippogriff (eagle-horse mix) is provoked and strikes a student; the same creature is executed by a hatchet (heard, not shown). A boggart in a class demonstration changes shape to match what students are most afraid of (and kids learn to fight their fears with laughter). A large dog breaks Ron's leg. Adult characters threaten to kill another. A werewolf chases Harry and Hermione. Harry believes he is marked for death and stalked by a murderer most of the school year.
