Folly of Love (German: Unfug der Liebe) is a 1928 German silent comedy film directed by Robert Wiene and starring Maria Jacobini, Jack Trevor and Betty Astor. While several of Wiene's previous films had met with mixed responses, Folly of Love was universally praised by critics. The film was made at the Marienfelde Studios of Terra Film. It was Wiene's last silent film. His next work was the 1930 sound film The Other.
