The Deep (1977)

In director Peter Yates' deep sea adventure, based on Jaws author Peter Benchley's best-selling book, about a couple who journeyed to Bermuda to dive at the wreckage sites of sunken ships:

• the beautiful cinematography of underwater diving, including the memorable opening title sequence - scuba diving images of sunken treasure divers David Sanders (Nick Nolte) and British girlfriend Gail Berke (Jacqueline Bisset) in a revealing white, clingy see-through T-shirt - during the dive, most audiences ignored Gail's discovery of an ampoule of an amber-colored liquid (medicinal morphine)

• their visit to crusty treasure hunter-expert Romer Treece (Robert Shaw) who asked about the ampoule: "Where'd you get this exactly?" - and the realization that there were more - over 90,000 ampoules of morphine in a sunken WWII freighter known as ‘The Goliath’ - sitting atop another sunken early 18th century Spanish ship
• the repeated full-screen, jump-scare appearances of a moray eel

Gail's Topless Strip in Front of 'Cloche' (Louis Gossett, Jr.)

• the threatening character of ruthless Haitian drug lord-dealer Henri 'Cloche' Bondurant (Louis Gossett Jr.), who ordered his thugs to search both Gail and Nick; Gail removed her bikini-top to bare herself before the drug lord to prove she wasn't hiding anything; he then threatened the two: "Be Off the Island By Tomorrow!"
• the scary and lengthy shark attack sequence
• the horrific voodoo ritualistic rape scene in which Gail was confronted by a Haitian practitioners in her hotel room who smeared rooster blood all over her naked mid-section
