(Directed by Alfred Hitchcock, starring Anthony Perkins and Janet Leigh.)
A thriller, that actually has a plot! And although a lot of people will remember Pyscho for a couple of brutal murders, that's not the main thrust of the film. It's more a case of making an issue of the detective work.
Marion Crane steals some money from her boss, and flees. She stays at a motel, where she meets the propietor (Norman Bates), who's not quite normal. She has second thoughts about what she's done, and decides to go back and return the money. But Norman has other some peculiar habits that stop that from ever happening.
The film was deliberately shot in black and white, supposedly to spare the audience from being to traumatised by the sight of blood (the bathroom scene is famous), even though the film was made in the era of colour films.
More recently, it's been remade (by someone else, and in colour). Though, like many remakes, it's quite dire. The acting is poor, and it's almost a verbatim copy of the original (most of the dialogue, camera shots, background music, etc.), with only a few embellishments. It's been re-set in the current time, even though the behaviour and dialogue of some of the characters hasn't been updated. All in all, pretty pointless.
