*Joy Will Prevail*: The Louis Kahn Biopic Plot Details and Production Status

The film, titled *Joy Will Prevail*, is a feature-length drama based on the life of Estonian-born American architect Louis Kahn (1901–1974), a man often cited as one of the most influential architects of the 20th century. While his public life was marked by iconic, monumental designs—such as the Salk Institute and the National Assembly Building of Bangladesh—his private life was notoriously complicated.

The Complex Narrative: Kahn's Three Families
