"You can call me Ed."
Apparently Elliott became Norman after E.T.'s gone and uses his wig, he also killed his mom Juliet and her lover Romeo. Better than Psycho III but I'd still prefer Psycho 2. A Little note: Herrmann's famous theme is not used in Psycho III.
Perhaps I'm crazy but this movie actually has good stuff in it! There's a scene straight out of Peeping Tom near the end, and the poisoning scene disturbs. Much more serious than the murdering in Psycho 2 & 3. The scene feels very carefully assembled much like the effect in Hitchcock's film: pulled into a ghost train of a dream. Olivia Hussey as Mother! not to mention the delicious deadpan acting of Anthony Perkins.
