Blair Maynard is a British-born Americanjournalist in New York City who was once in the Navy and who decides to investigate the mystery of why so many boats disappear in the Bermuda Triangle of the Caribbean. He takes his estranged son Justin with him to Florida with the promise of a vacation to Disney World and, while fishing, both are attacked by an unkempt man and forcibly brought to an uncharted island. On the island, Blair discovers that the inhabitants are a centuries-old colony of savage Frenchpirates.
The group has been living on the island for centuries, unseen by society (except for an English archeologist obsessively keeping their secret) and sustain themselves by raiding pleasure boats. The pirates kill whoever comes to the island; however, Blair and his son are both kept alive due to a false assumption that they are descended from Robert Maynard and a need to offset the negative effects of inbreeding. Blair is used to impregnate a female and act as a scribe for the largely illiterate group, while Justin is brainwashed to become a surrogate heir to Nau, the pirate leader. Blair struggles to escape from the island, but all attempts fail.
Blair begins his captivity as a very peaceable and civilized everyman, but he is helpless in the absence of law and the presence of the almost unlimited violence the pirates commit. Subjecting him to constant fear and abuse, the pirates fail to realize how desperate Blair is becoming as his repeated escape attempts fail. He eventually arranges for the pirates to come head to head with a US Coast Guard cutter, but they manage to wipe out the crew and take over the vessel. Blair sneaks aboard and, while most of the pirates are gathered on the aft deck of the ship, discovers a deck-mounted M2 machine gun hidden underneath a tarp. He opens fire on the pirates, and continues to fire even after they are all dead.
He then learns that Nau was not on the deck. The two men then stalk each other through various parts of the decimated vessel. Blair eventually gets the upper hand and kills Nau with a flare gun. Blair and his son, who no longer desires to be a pirate and seems much more respectful of his father, are reunited.
Richard Zanuck and David Brown paid Benchley $2.15 million for film rights to the novel and a first draft screenplay, as well as a guarantee of 10 percent of the gross, five percent of the soundtrack sales, and approval of the crew and locations,[2][3] which at the time was the largest amount ever paid for film rights to any book.[4] Benchley later claimed that he could have been able to retire if the film was more successful.[2] Brown said the budget was $12 million plus 25% overhead but other reports put it over $20 million.[5] Principal photography took place between May 14 and August 23, 1979.[2] The film was mostly shot on the islands of Antigua and Abaco,[5] and the United States Coast GuardcutterDauntless stands in for the fictitious USCGC New Hope in the movie. Some scenes were also shot in the British West Indies and Florida at Miami and Fort Lauderdale.[2]
On Rotten Tomatoes, the film holds an approval rating of 33% based on six reviews, with an average rating of 4.8/10.[9]
Author and film critic Leonard Maltin awarded the film a BOMB, his lowest rating, calling it "[an] Absolutely awful thriller", and criticized Warner's casting as "the most normal guy on the island".[10] Donald Guarisco from Allmovie gave the film a more positive review, calling Benchley's script "dark and witty, with gruesome violence, black humor". Guarisco summarized in his review by writing, "The Island is not for everybody but fans of big-budget oddities are likely to be fascinated by the well-funded eccentricity at play here."[11]
