Based on an original 1955 Disneyland ride - designed by Walt Disney himself (he was the Skipper).
Was in development since 2003 when Pirates of the Caribbean: Curse of the Black Pearl was a success and proof that rides could create film franchises.
Indiana Jones and specifically the Ark of the Covenant served as inspiration to the film myths and legend aspect while The African Queen and Romancing the Stone led to the main protagonist's love story.
