Trivia, insights & behind the scenes
The film's marketing leaned heavily on Bisset's underwater scenes, creating the wet t-shirt phenomenon that overshadowed the actual treasure plot.
Robert Shaw filmed this between Jaws and dying in 1978. His character's underwater death is eerily prophetic given his real-life heart condition.
