==Film sequels==
===''Psycho II''===
In 1983's ''[[Psycho II (film)|Psycho II]]'', the first sequel to the original film, Norman is released from the institution twenty-two years after his arrest, seemingly cured. Sam Loomis has passed away at this point. Norman meets Mary Samuels ([[Meg Tilly]])—later revealed to be Mary Loomis, Lila and Sam Loomis's daughter and Marion Crane's niece—and falls in love with her. However, a series of mysterious murders occurs, as well as strange appearances and messages from his mother, and Norman slowly loses his grip on [[sanity]]. The mysterious appearances and messages turn out to be a plot by Lila to drive him insane again in order to get him recommitted. The actual murders turn out to be the work of Norman's coworker, [[Emma Spool]] ([[Claudia Bryar]]). Before Norman discovers this, however, Mary Loomis is shot dead by the police during a confrontation with Norman, and Mrs. Spool murders Lila. When Spool tells Norman that she is his real mother, he kills her and [[embalming|embalms]] her corpse while assuming the "Mother" personality once again.<ref name = "PsychoTwo">{{cite video|people = Richard Franklin (Director)|title = [[Psycho II (film)|Psycho II]]|medium = DVD|location = United States|publisher = [[Universal Pictures]]|date=June 3, 1983}}</ref>

===''Psycho III''===
In 1986's ''[[Psycho III]]'', set a month later, Norman continues to struggle, unsuccessfully, against "Mother"'s dominion. He also finds another love interest named Maureen Coyle ([[Diana Scarwid]]), who eventually dies at "Mother"'s hand. In the film, Mrs. Spool's corpse is first discovered by sleazy musician Duane Duke ([[Jeff Fahey]]), whom Norman kills when Duke tries to use the discovery to [[blackmail]] Norman. Tracy Venable ([[Roberta Maxwell]]), a reporter interested in Norman's case, finds out that Spool was in fact Norman's aunt—Norma Bates' sister—who was in love with Norman's father and killed him when he chose Norma over her. She then kidnapped the child Norman, believing him to be her own, but she was arrested and institutionalized, leaving Norman to be raised by Norma.

"Mother" orders Norman to kill Tracy, but in the end he destroys Spool's corpse, attempting to break free of her control. He is then arrested and put back in the institution.<ref name = "PsychoThree">{{cite video|people = [[Anthony Perkins]] (Director)|title = [[Psycho III]]|medium = DVD|location = United States|publisher = [[Universal Pictures]]|date= July 2, 1986}}</ref>

===''Psycho IV: The Beginning''===
''[[Psycho IV: The Beginning]]'' (1990), the final film in the series, [[retroactive continuity|retcons]] the revelations of the second film and third film, supplying that Norman's father was stung to death by bees and removing all references to Emma Spool. In this film, Norman has been released from an institution, and is married to one of the hospital's psychologists, a woman named Connie ([[Donna Mitchell]]). When his wife becomes [[pregnancy|pregnant]], he lures her to his mother's house and tries to kill her, wanting to prevent another of his "cursed" line from being born into the world; the film implies that Mrs. Bates ([[Olivia Hussey]]) suffered from [[schizophrenia]] and [[borderline personality disorder]] and passed the illnesses on to her son. However, he relents at the last minute, when Connie professes her love for him. He then burns the house down in an attempt to free himself of his past. During the attempt, he is tormented by [[hallucination]]s of "Mother" and several of his victims, becoming injured in a fall. He almost dies in the flames before willing himself to get out, apparently defeating his illness at long last; he is finally free of his mother's voice, which demands to be let out. This was Anthony Perkins' final performance as Norman Bates; [[Henry Thomas]] portrayed Norman as a teenager.<ref name = "PsychoFour">{{cite video|people = [[Mick Garris]] (Director)|title = [[Psycho IV: The Beginning]]|medium = DVD|location = United States|publisher = [[Universal Television]]|date= November 10, 1990}}</ref>
