Earlier in this forum, it's speculated that the Pirates of the Caribbean films are derived from Captain Blood. For sure -- but there was an intermediary, the Pirates of the Caribbean ride in the New Orleans Quarter at Disneyland.
PoC was envisioned as a wax museum when Disneyland was being designed in the 1950s, but the amazing "dark ride" opened in 1967. It tells a story in linear fashion of a pirate raid on a tropical city. The story is definitely this movie's, except that Disney, ever the law-and-order freak, changed the ending to have the pirates imprisoned and hung (humorously, of course), not feted as heroes. The films with Johnny Depp followed four decades later.
PoC, now also a videogame, remains one of Disneyland's coolest attractions, literally as well as figuratively. I never pass up a chance to dine at the Blue Bayou restaurant, faux fireflies buzzing around, watching the small boats set off for a trip to Far Tortuga and adventure!
