Step 1 : Introduction to the question "Which American movie was the first to show a toilet flushing on screen?"

The master of suspense Alfred Hitchcock's psychological horror-thriller film Psycho terrified audiences in 1960. It opened in theatres amidst great secrecy, and instructions that no patrons would be admitted once the film started. It served as the "mother" of all modern horror suspense films, shocking audiences with its infamous 45-second “shower scene”. It was also the first American film ever to show a toilet flushing on screen. No flushing toilet had appeared in film and television in the United States at that time. Psycho is now considered one of Hitchcock's best films and praised as a major work of cinematic art.
