Simply pretending to be murdered in the shower was enough to keep this star from ever taking one again!

The moment you see a familiar scene in a scary movie, you're most likely going to avoid getting into that situation for a while. Character get attacked by a monster in the dark basement? Hit the lights and spend as little time down there as possible. Little kid find some demented toy under their bed? Board it up and avoid letting your leg hang down there! Turns out it's the same thing for the actors that portray the victims. Janet Leigh, the actress from the famous shower scene in “Psycho,” only took baths for the rest of her life!

Filming the actual scene wasn't the nail in the coffin, she was still partial to showers up until she saw the scene on the big screen. Perhaps it's having the cast and crew standing around or the constant cutting and re-filming, but the final product had a profound effect on her. She realized how vulnerable a person is while in the shower and vowed only to take baths for the rest of her life—though there are plenty of movies of helpless characters getting attacked in the tub too.

As a bonus fun fact: The leading cause of death and injury in the home is falling, likely in the shower—not murderous psychos!
