Rebello's carefully researched book tells us everything we could ever want to know about the making of psycho. Starting from the gruesome crimes that inspired the novel on which the film is based, he takes us through the novel's adaptation into a screenplay and the film's preproduction, shooting, postproduction, and ultimate reception. Rebello's technique is as painstaking and thorough as
Hitchcock's--he includes an incredible amount of detail and in doing so reveals what mattered the most to Hitchcock in the process of making his movies.
