<P> The screenplay is relatively faithful to the novel, with a few notable adaptations by Hitchcock and Stefano . Stefano found the character of Norman Bates--who, in the book, is middle - aged, overweight, and more overtly unstable--unsympathetic, but became more intrigued when Hitchcock suggested casting Anthony Perkins . Stefano eliminated Bates' drinking, which evidently necessitated removing Bates' "becoming" the Mother personality when in a drunken stupor . Also gone is Bates' interest in spiritualism, the occult and pornography . Hitchcock and Stefano elected to open the film with scenes in Marion's life and not introduce Bates at all until 20 minutes into the film, rather than open with Bates reading a history book as Bloch does . Indeed, writer Joseph W. Smith notes that, "Her story occupies only two of the novel's 17 chapters . Hitchcock and Stefano expanded this to nearly half the narrative". He likewise notes there is no hotel tryst between Marion and Sam in the novel . For Stefano, the conversation between Marion and Norman in the hotel parlor in which she displays a maternal sympathy towards him makes it possible for the audience to switch their sympathies towards Norman Bates after Marion's murder . When Lila Crane is looking through Norman's room in the film she opens a book with a blank cover whose contents are unseen; in the novel these are "pathologically pornographic" illustrations . Stefano wanted to give the audience "indications that something was quite wrong, but it could not be spelled out or overdone ." In his book of interviews with Hitchcock, François Truffaut notes that the novel "cheats" by having extended conversations between Norman and "Mother" and stating what Mother is "doing" at various given moments . </P> <P> The first name of the female protagonist was changed from Mary to Marion, since a real Mary Crane existed in Phoenix . Also changed is the novel's budding romance between Sam and Lila . Hitchcock preferred to focus the audience's attention on the solution to the mystery, and Stefano thought such a relationship would make Sam Loomis seem cheap . Instead of having Sam explain Norman's pathology to Lila, the film uses a psychiatrist . (Stefano was in therapy dealing with his relationship with his own mother at the time of writing the film .) The novel is more violent than the film; for instance, Crane is beheaded in the shower as opposed to being stabbed to death . Minor changes include changing Marion's telltale earring found after her death to a scrap of paper that failed to flush down the toilet . This provided some shock effect, since toilets were virtually never seen in American cinema in the 1960s . The location of Arbogast's death was moved from the foyer to the stairwell . Stefano thought this would make it easier to conceal the truth about "Mother" without tipping that something was being hidden . As Janet Leigh put it, this gave Hitchcock more options for his camera . </P> <P> Paramount, whose contract guaranteed another film by Hitchcock, did not want Hitchcock to make Psycho . Paramount was expecting No Bail for the Judge starring Audrey Hepburn, who became pregnant and had to bow out, leading Hitchcock to scrap the production . Their official stance was that the book was "too repulsive" and "impossible for films", and nothing but another of his star - studded mystery thrillers would suffice . They did not like "anything about it at all" and denied him his usual budget . In response Hitchcock financed the film's creation through his own Shamley Productions, shooting at Universal Studios under the Revue television unit . The original Bates Motel and Bates house set buildings, which were constructed on the same stage as Lon Chaney Sr.'s The Phantom of the Opera, are still standing at Universal Studios in Universal City near Hollywood and are a regular attraction on the studio's tour . As a further result of cost cutting, Hitchcock chose to film Psycho in black and white, keeping the budget under $1,000,000 . Other reasons for shooting in black and white were his desire to prevent the shower scene from being too gory and his admiration for Les Diaboliques's use of black and white . </P> <P> To keep costs down, and because he was most comfortable around them, Hitchcock took most of his crew from his television series Alfred Hitchcock Presents, including the cinematographer, set designer, script supervisor, and first assistant director . He hired regular collaborators Bernard Herrmann as music composer, George Tomasini as editor, and Saul Bass for the title design and storyboarding of the shower scene . In all, his crew cost $62,000 . </P>
