Million Dollar Mermaid tells the story of Australian swimming sensation Annette Kellerman, who overcame childhood polio to go on and achieve fame as a professional swimmer and film star in the early decades of the 20th century. At the same time, she scandalized the world by wearing a one-piece bathing suit on public beaches long before the style was accepted in polite company, and made waves in other ways as well.

A musical romantic drama, this biopic tells the story of influential Australian swimmer Annette Kellerman (Esther Williams), who broke gender barriers while becoming a pioneer of synchronized swimming. Following her father (Walter Pidgeon) from Australia to London, Kellerman combines her passion for dance with her talents as a swimmer, coming of age while learning about love and show business, and working against the inherent repression of female expression in the early 20th century.

Starring Frank Ferguson, Esther Williams, Victor Mature, Walter Pidgeon, David Brian.
