The Black Pirate
This movie was released on March 8, 1926. Many of the scenes were filmed on or around California's Santa Catalina Island. To perfect his form, Douglas Fairbanks was said to be taking lessons in knife throwing, using a cutlass, as well as swimming lessons with swimming champion Johnny Weissmuller. Weissmuller later transitioned to movies and television.
Fortunately, copies of this film do exist and are available on Youtube for your viewing pleasure.
