Shipwrecked [1990]

Based on the novel Haakon Haakonsen, Shipwrecked is a family film about a cabin boy (Stian Smestad) whose ship is hit by a hurricane just before it is about to be ambushed by pirates. The boy and his stowaway friend wash up on a South Seas island which happens to be where the pirates' treasure is buried. Soon, the pirates--led by Lieutenant Merrick (Gabriel Byrne)--arrive at the island with hopes of reclaiming their treasure, and the boy decides to construct a series of elaborate booby traps to prevent them from reaching the booty.
