* AffectionateParody / AdamWesting: Anthony Perkins hosted an episode in the first season of ''SaturdayNightLive,'' which included an [[http://www.youtube.com/watch?v=bhhTb4SoaaU almost-obligatory, and hysterical, Norman Bates skit]].
** In 1990 (the same year that ''the Beginning'' was released), Perkins did an [[http://www.youtube.com/watch?v=705jPpxq1JQ oatmeal commercial as Norman Bates.]]

* BlackSheepHit: The original book was this for RobertBloch, most of whose horror fiction involved the CthulhuMythos.
* DirectedByCastMember: Anthony Perkins directed the third movie.
* DoingItForTheArt: Hitchcock went to a ''lot'' of trouble to try and avoid the film's twists being revealed. Most notably, he went about buying up copies of the source novel out of his own pocket.
* EnforcedMethodActing: Hitchcock allowed both Perkins and Leigh to improvise their roles as long as it didn't involve moving the camera. Norman's habit of munching candy is an example.
* GenreKiller: Many film historians consider ''Psycho'' to the be movie that killed FilmNoir, as the purpose of the first hour or so is to continuously set up and subvert the tropes of that genre.
* PlayingWithCharacterType: Bates initially appears to be the same sort of character Perkins was known for playing up to that time - a likeable, socially awkward supporting role. This makes the TwistEnding all the more shocking.
* RealLifeRelative: The brief appearance of young Norman in ''Psycho II'' was by Anthony Perkins' son, Oz.
* RoleAssociation: Mr. Cassidy is [[Film/ItsAWonderfulLife Sam Wainwright]]. California Charlie is [[{{MacGyver}} MacGyver's grandfather]]. And the psychiatrist is [[KolchakTheNightStalker Kolchak's boss]]--or [[Film/WestSideStory Lieutenant Shrank]].
** Look closely after the psychiatrist scene, when the cop takes the blanket to Norman. See the other, non-speaking cop who's standing guard outside the door? It's a young [[TheMaryTylerMooreShow Ted Baxter]]!
* StarDerailingRole: Subverted yet played straight: History will tell you that ''Psycho'' was not a box-office nor a critical failure, and it's obviously considered one of the best films ever made. However, many consider it to be the film that simultaneously heightened and ruined Anthony Perkins's career as an actor because he was subject to typecasting afterwards, and most moviegoers [[IAmNotSpock only knew him as Norman Bates]]. Perkins never had any [[CreatorBacklash backlash]] because of it, but plenty of his fans will vouch Perkins was one of the most underrated actors in Hollywood history, and ''Psycho'' is to blame.
** Ironically enough, at the time ''Psycho'' was Perkins PlayingAgainstType. After ''Psycho,'' if there was a movie where he wasn't playing a "psycho," it was him playing against type again.
** The same applies to Janet Leigh. Although not subject to typecasting afterwards, pretty much all she is really remembered for was the shower scene.
* ThrowItIn: Location shooting (for the scene where Marion drives out of town with the money) was done in downtown Phoenix in December 1959. After [[DidIMentionItsChristmas Christmas decorations]] were discovered to be visible in the footage, a graphic was added to the beginning of the film setting the date as "Friday, December the Eleventh".
** Also, Norman's CharacterTic of eating candy was a suggestion of Perkins's that Hitchcock happened to like.
* WhatCouldHaveBeen: Hitchcock originally wanted the shower scene to play without music, but Herrmann begged him to try it. Yes, the TropeMaker for PsychoStrings very nearly didn't come about at all.
