The Lost Continent is a crazy-quilt of a film, with chunks of several unrelated plotlines sewn together willy nilly. Eric Porter plays Lansen, the captain of a tramp steamer who has agreed to deliver contraband dynamite for a hefty price. His passengers are a polyglot of the good, the bad and the worse. Shipwrecked on an mysterious isle in the Sargasso Sea, Lansen and party find themselves prisoners of a bizarre inbred colony still governed by the long-abandoned edicts of the Spanish Inquisition. The film is no more coherent than the original Dennis Wheatley novel Uncharted Seas, but that doesn't detract from its endearing wackiness. To their credit, the cast members of Lost Continent play the script straight, which merely adds to the kinky fun.
