In the 1930s, Greta Garbo was one of the biggest stars in the world. Her line "I want to be alone" from Grand Hotel (1932) became one of the most famous in film history.
In 1941, at just 36, she made Two-Faced Woman and never made another movie. She spent the next five decades living quietly in New York, turning down every offer to return, until her death in 1990.
