We have finished watching Psycho now and it would be good if you sought out some background information on the film. One place to start is Filmsite which has a great review on the film with lots of background information. Here’s a little:
Alfred Hitchcock’s powerful, complex psychological thriller, Psycho (1960) is the “mother” of all modern horror suspense films – it single-handedly ushered in an era of inferior screen ‘slashers’ with blood-letting and graphic, shocking killings (e.g., Homicidal (1961), The Texas Chainsaw Massacre (1974), Halloween (1978), Motel Hell (1980), and DePalma’s Dressed to Kill (1980) – with another transvestite killer and shower scene). While this was Hitchcock’s first real horror film, he was mistakenly labeled as a horror film director ever since.
The nightmarish, disturbing film’s themes of corruptibility, confused identities, voyeurism, human vulnerabilities and victimization, the deadly effects of money, Oedipal murder, and dark past histories are realistically revealed. Its themes were revealed through repeated uses of motifs, such as birds, eyes, hands, and mirrors.
