Porco Rosso, known in Japan as Crimson Pig (紅の豚, Kurenai no Buta) is the sixth anime film directed by Hayao Miyazaki, produced by Studio Ghibli and released in 1992. The story is about an Italian World War I fighter ace, now living as a freelance bounty hunter chasing "air pirates" in the Adriatic Sea. The man has been cursed and transformed into a pig. Once called Marco Pagot, he is now known to the world as "Porco Rosso", Italian for "Red Pig".
The film is loosely based on Miyazaki's manga Hikōtei Jidai. Miyazaki apparently based the scenery on the Rijeka, former Fiume, island coastline in Croatia.
During the 1920s, Porco Rosso is a former WW1 Italian flying ace who works as a freelance pirate hunter.
