Laputa: Castle in the Sky (天空の城ラピュタ, Tenkū no Shiro Rapyuta?) (re-titled just Castle in the Sky for release in the United States) is a film written and directed by Hayao Miyazaki, released in 1986. It is the first film created and released by Studio Ghibli, although is considered the second by some since Nausicaä of the Valley of the Wind was created by the founding members two years before. Laputa: Castle in the Sky won the Animage Anime Grand Prix in 1986. The name Laputa comes from the name of the floating island in Jonathan Swift's novel Gulliver's Travels.
