Fan Casting Tim Burton’s Aquaman (1997)

Arthur confronts pirates hijacking a Russian Akula-class submarine. Their leader is killed in a failed attempt to kill Arthur, and the leader's son David vows revenge. The present king Orm Marius, Orvax's son (who is now Atlantis's new ruler after his father died) and Arthur's younger half-brother, convinces King Nereus of Xebel to help unite Atlantis and destroy the surface world for polluting the oceans. If Orm unites all four kingdoms, he will receive the title of Ocean Master, commander of the most powerful force on the planet. Nereus agrees to help after they are attacked by the hijacked submarine.
