Everyone is at least familiar with Alfred Hitchcock, especially iconic classics, such as Psycho and The Birds. But for some reason his adaptation of a stage play that’s right up his alley tends to get overlooked. Obviously, there’s dramatic tension in a slashing knife, a flock of pecking birds, or any other bloody spectacle. But what makes this film so chilling is its plausibility; impressionable people can easily take a hypothetical concept, such as “the perfect crime” too far. Waaay too far.
