You watch The Wizard of Oz and know all about the grand glory and sad hardships of Judy Garland's life. You see Rita Hayworth on the screen as Gilda and know she died of Alzheimer's. Or James Dean in any of the few movies he made dying at such a young age in a car crash. Allegedly his heart was broken when Pier Angeli married Vic Damone. Or Natalie Wood as Gypsy Rose Lee knowing she drowned with some mystery surrounding it decades later. Or Robin Williams as Mork or Mrs. Doubtfire or just himself cracking up audiences with his zany brilliance knowing how his life ended. Bittersweet.
