The Corsican Brothers

The Corsican Brothers is a 1941 swashbuckler film starring Douglas Fairbanks Jr. in a dual role as the title Conjoined twins, separated at birth and raised in entirely different circumstances. Both thirst for revenge against the man who killed their parents, both fall in love with the same woman. The story is very loosely based on the 1844 novella Les frères Corses by French writer Alexandre Dumas, père.
