Krakatoa, East of Java is a 1968 American disaster film starring Maximilian Schell and Brian Keith. During the 1970s, the film was re-released under the title Volcano.
The story is loosely based on events surrounding the 1883 eruption of the volcano on the island of Krakatoa, with the characters engaged in the recovery of a cargo of pearls from a shipwreck perilously close to the volcano.
The film was nominated for the Academy Award for Best Special Visual Effects.
Famously, the movie's title is inaccurate: Krakatoa actually is west of Java, but the movie's producers thought that "East" was a more atmospheric word, as Krakatoa is located in the Far East.
