The Mysterious Lady (1928) is a Metro-Goldwyn-Mayer silent film romantic drama, starring Greta Garbo, Conrad Nagel, and Gustav von Seyffertitz, directed by Fred Niblo, and based on the novel War in the Dark by Ludwig Wolff.

Greta Garbo was a Swedish-American actress and a premiere star during Hollywood's silent and early golden eras. Regarded as one of the greatest screen actresses of all time, she was known for her melancholic and somber screen persona, her film portrayals of tragic characters, and her subtle and understated performances. In 1999, the American Film Institute ranked Garbo fifth on its list of the greatest female stars of classic Hollywood cinema.
