When Garbo Talks! is a world premiere musical about Greta Garbo set during Hollywood's Golden Age and the transition from silent films to talking pictures. Seventeen-year-old Swedish acting student Greta Gustafsson is discovered by Sweden's genius film director, Mauritz Stiller. Stiller uses her talent to angle his way into Hollywood, but MGM's Louis B. Mayer has plans of his own. Hearts break and careers plummet when the emboldened 24-year-old Greta Garbo challenges Mayer and the Hollywood establishment to become MGM's highest paid actress and most reluctant international star.
