The best way to look at this movie is not as the story of Alfred Hitchcock making Psycho. This movie is about what it was like to be married to Alfred Hitchcock while he was making Psycho. While Helen Mirren receives second billing behind Anthony Hopkins, she is very much in the foreground as Alma, the woman behind the Master of Suspense through much of his career, and it is her performance that carries this movie.
In a strange way, Little Miss Sunshine is the film that The Royal Tenenbaums could have been. Both movies focus on extended families who are dysfunctional to a comic extreme. But while the rich but unhappy family in Wes Anderson’s film often just seemed annoyingly arch, little Olive Hoover (Abigail Breslin) and her thoroughly middle-class Albuquerque household are sympathetic, full-blooded characters.
