“Dating Her is Like Wearing Hot Lava.”: These Wild Facts About Celebrities Left Us Speechless

Jack Nicholson already had a reputation for being unpredictable, but The Shining gave him one of the most famous moments of his career. During the terrifying bathroom-door scene, Nicholson smashed through the wood and delivered a line that was not originally scripted. “Here’s Johnny!” came straight from his own improvisation.
