Blue Island (Italian title Due gocce d'acqua salata) is a 1982 film directed by Luigi Russo (under the pseudonym John Wilder) and Enzo Doria, who also co-wrote the screenplay with Dardano Sacchetti. Filmed in the Seychelles, it stars Fabio Meyer, Mario Pedone and Sabrina Siani. Like the film Paradise of the same year, it was inspired by the success of the 1980 release The Blue Lagoon.
