Argus Filch
Accompanied by his loyal companion, the cat Mrs. Norris, Argus Filch, the irritable caretaker of Hogwarts, patrols the school's corridors with a perpetual scowl. His appearance complements his sour disposition, and he is described as possessing thin gray hair and a hunched back.
David Bradley masterfully embodied this character, convincing audiences of his relish for disciplining students when rules were broken. His portrayal in the movie closely aligns with the eerie image portrayed here.
