Janet Leigh and Psycho

Janet Leigh is most famous for the shower scene in Alfred Hitchcock's Psycho. 

Although the scene traumatized her of taking showers for the rest of her life, she was nominated for an Academy Award for Best Supporting Actress and won the Golden Globe Award for Best Supporting Actress in 1960. 

The crew of Psycho used to hide skeletal "Mother" dolls in different places in Leigh's dressing room to scare her!
