Brigitte Bardot at age 20 in ‘Doctor at Sea’

Brigitte Bardot leans back and turns on the va-va-voom in the 1955 film Doctor at Sea. Brigitte Bardot was born on September 28, 1934, so she was almost certainly age 20 when this photo was taken during filming. By this point Bardot was already a successful model and budding movie star; Wikipedia calls this comedy "her first sizable English-language role." Bardot played a French nightclub singer who eventually falls for the film's star, Dirk Bogarde, and (no surprise) vice-versa on Bogarde's part.
