Originally envisioned in the late 1950s as a walk-through wax museum featuring pirates from history, the attraction evolved into a boat ride through complex show scenes filled with Audio-Animatronics characters after the 1964 New York World's Fair, which brought about several advances in Disney's theme park technologies. Instead, humorous sketches of fictional pirates by Imagineer Marc Davis inspired the animatronic diorama seen throughout the final attraction. Opening on March 18, 1967, Pirates of the Caribbean was Disneyland's largest Audio-Animatronics project to date and was the last attraction Walt Disney was involved in designing. The portrait of the female pirate above the bar in the Crews Quarters scene is an original work by Davis. The pirate captain in the scene where captured women are auctioned as brides is a test bed for updates and developments to Audio-Animatronics technology; many innovations are tried on him first. As a result, his movements are far more lifelike and expressive than virtually any other Audio-Animatronics figure in all of Disneyland. The ride never was intended to be part of the Magic Kingdom at Walt Disney World Resort because of concerns that it would not be exotic enough due to Florida's geographic proximity to the Caribbean and New Orleans, the settings of the Disneyland attraction. Instead, Imagineers developed plans for a similar attraction called the Western River Expedition, which would have featured cowboys and Indians instead as well as banditos, coyotes, miners, and a climatic drop bigger then Pirates. After many Walt Disney World guests complained about the lack of Disney's celebrated pirate attraction, an abbreviated version opened in Florida on December 15, 1973. The attraction was part of the opening day of Tokyo Disneyland (April 15, 1983) and of Disneyland Paris (April 12, 1992). There is no Pirates of the Caribbean attraction at Hong Kong Disneyland, but there are plans to add it in the near future with some Splash Mountain-style elements
