Portions of Un magnifique salaud (1956) were shot on location in St. Thomas in the Virgin Islands, as well as San Juan, Puerto Rico. Location filming in the Virgin Islands was initially delayed, as the film crew arrived in St. Thomas at same time as hurricanes "Connie" and "Diane." Due to the emergency, the production agreed to temporarily turn over its equipment trucks to the local authorities in order to help with the evacuation of the island's remotest population.
