Psycho

Psycho redefined cinematic horror with its shocking narrative twist and groundbreaking techniques. Made for just $800,000, it grossed $32 million, a 40-to-1 return that dwarfs the average horror film’s profitability. The notorious 45-second shower scene, filmed with 78 camera setups, set a benchmark for suspense that even The Shining cannot surpass in pure shock value.
