Fanciful, disturbing, and wildly original, it announces the arrival of a fresh, bold voice in American cinema.

Great example of an old-fashioned, pure-at-heart escapist event movie that doesn't pretend to be anything that it's not and has boat loads of fun being its own ludicrous self.

Through painfully honest and emotional moments, the movie becomes irresistibly relatable

The story, direction, characters, and writing/dialogue is akin to taking a tranquilizer shot to the neck, but everything else was so well done.

I love Robert Shaw and Eli Wallach, both two great great actors. Eli Wallach has a small, insignificant role in this. Robert Shaw is good but I love him much more in "From Russia with Love", "Battle of the Bulge", "The Sting" and especially in "A Man for All Seasons". Jacqueline Bisset is young and beautiful. Same Nick Nolte. Here he is not the great actor from later roles like in "Down and Out in Beverly Hills" or "Cape Fear". Beautiful underwater filming by Christopher Challis. When I first saw it, about 40 years ago, I liked it more (I was about 20 years old). Watched again in 2018, I find it static, monotonous, boring, does not have the same charm.

A simple film of the 1970s intended to frighten you a little bit, to keep your interest with some suspense, and to play on some dreams about treasures and fears about drugs and drug dealers.The way there were spaghetti westerns there were shark-friendly sea movies too. That was just after Jaws (1975) and this film plays with sharks but without too much blood and no damage to humans. The sharks are only lured into attacking a certain zone by some drug dealing Blacks – who are naturally black of course in the drug dealing business whereas the whites are in the treasure hunting business, that may also be morphine – to trap the afore-mentioned white treasure hunters who are in the deep, well not too deep though.Then you just need an old French tobacco ship used by the Spanish governor of Cuba to transport the three key lock chest in which he is smuggling some Spanish King's lost valuable back to Europe while he is trying to appropriate them to himself at the same time. In other words he is a bad and thieving magpie of a governor.It all ends well of course. The Blacks are all killed or nearly, though they kill one white man and try to kill another one, plus the girl, because there is a girl of course. What could sailors do without a girl to keep them warm when the sailors are in port? A beautiful explosion of the tip top of a lighthouse and another of a sunk ship that creates some trouble at the surface of the ocean but NOT ONE dead fish. Dynamite is no longer what it used to be. That might have been cruel with the live sea food down there if a bunch of plastic semblances had floated on the surface. That's a pleasant change from serious British comedy like "Only Fools and Horses."Enjoy the waves.Dr Jacques COULARDEAU

I loved this movie when I first watched it in 1977 as a 32-year old and I love it just as much today. It has everything that a "boy's own" adventure could offer; a decent plot, a beautiful girl (let's face it, Jacqueline Bisset is gorgeous at the best of times but put her in a wet T-shirt and she's, well, WOW!, a fabulous exotic location, a dastardly villain or two and a couple of decent goodies to battle the baddies. Toss in a great music score by John Barry (that theme is brilliant) and what more could you ask for?Robert Shaw plays a great part and is equalled only by Eli Wallach; he was always an excellent baddie! Nick Nolte may not be the world's greatest actor but he does the job okay in this movie.

It was based on a Peter Benchley novel and had Robert 'Captain Quint' Shaw but despite these and many other references to 'Jaws' (including a brazenly misleading 'monster movie' styled poster), 'The Deep' was a beached whale. Long, drawn-out and tedious in the extreme, 'The Deep' was everything 'Jaws' wasn't, sporting everything from stunningly dull editing to ropey special effects (the lunging 'moray eel' looked like it was carved out of something very wooden) thinly-sketched and unlikeable characters. Robert Shaw is all shouty and hammy with a wobbly 'Irish' accent, Nick Nolte is as wooden as a barge-pole and Jaqueline Bisset is totally wasted (except as a hot body) in a bimbo-ish part more suited to the talents of Farrah Fawcett (i.e. she's either asking blatantly expositional questions or being menaced as a damsel in distress). The plot is confused and poorly conveyed, as well as the whole thing being a good half hour too long. Not a lot of fun.
