Hitchcock hired writer James Cavanaugh to write a draft of the screenplay. Unsatisfied with Cavanaugh's screenplay, Hitchcock then hired up-and-coming writer Joseph Stefano to adapt the novel. The film began shooting in December 1959 and would go on to last about a month. It was filmed mostly on the backlot of Universal and in various sound stages. During shooting, Hitchcock was forced to uncharacteristically do retakes for some scenes. The final shot in the shower scene, which starts with an extreme close-up on Marion's eye and pulls up and out, proved very difficult for Leigh, since the water splashing in her face made her want to blink, and the cameraman had trouble as well since he had to manually focus while moving the camera. Retakes were also required for the opening scene, since Hitchcock felt that Leigh and Gavin were not passionate enough. Leigh had trouble saying "Not inordinately" for the real estate office scene, requiring additional retakes. Lastly, the scene in which the mother is discovered required complicated coordination of the chair turning around, Miles hitting the light bulb, and a lens flare, which proved to be the sticking point. Hitchcock forced retakes until all three elements were to his satisfaction. The famous shower scene took a week to complete and took up a third of Janet Leigh's shooting time. "Psycho" was released on June 16, 1960 to mixed critical reception and financial success, making thirty-two million dollars in its theatrical run. The film received four Academy Award nominations.
