Through research in Treece's library, they reconstruct the history of the lost treasure ship, locate a list of valuable items, including a gold pinecone filled with pearls, with the letters "EF" engraved on it, and learn that it identifies Elisabeth Farnese, a noblewoman for whom they were made by the King of Spain. Sanders is determined to locate at least one item on the list to establish provenance, since without it there is no real value to the treasure. Treece wishes to destroy the Goliath to put the morphine out of reach of Cloche, and Cloche interferes with their efforts so that he can recover the morphine for himself. During a running series of conflicts, Treece's friend Kevin is murdered by one of Cloche's henchmen. Adam betrays them and is killed when he triggers a booby-trap while trying to steal the recovered morphine. A climactic battle during the final dive ensues, with Cloche (who is killed by the giant eel) and his divers being killed in the destruction of the Goliath and the recovery of a gold dragon necklace that will provide the needed provenance of the treasure. Cast Two actors from the Jaws films (which were also based on a novel by Peter Benchley) appeared in this film. Robert Shaw played shark hunter "Quint" in Jaws in 1975, while Louis Gossett Jr. would later go on to play SeaWorld park owner "Calvin Bouchard" in Jaws 3 in 1983. Shaw's character Romer Treece was largely inspired by Bermudian explorer Teddy Tucker who makes a cameo appearance as the Harbor Master early in The Deep. Tucker's own dive boat The Brigadier was dressed to play Treece's boat Corsair and it was on that vessel that Peter Benchley partly wrote Jaws. Production The original concept was developed from the story of a Bermuda shipwreck, the Constellation, which sank in 1942, carrying ampoules of morphine among other war cargoes, such as concrete and pharmaceuticals. Constellation sank after possibly striking the wreckage of American Civil War blockade runner Montana, which Peter Benchley described as having sunk one on top of the other. After the success of Jaws, Columbia Pictures purchased the rights to Benchley's next novel before its publication in 1976, hiring him to write a screen adaptation. After Peter Guber left his job at Columbia and signed a three-year distribution deal between Columbia and his new company Casablanca FilmWorks, he received The Deep
