The affair
This subplot was jarring, and anyone reading Benchley’s novel should go in with a warning that the love affair between Matt Hooper — a shark expert called into town to help with their shark problem — and Ellen Brody is graphic in detail. The guess here is the producers and Spielberg couldn’t eliminate this storyline fast enough. In the novel, Chief Martin Brody’s wife, Ellen, dreams of her past affluent lifestyle before her marriage. In another odd twist, Ellen dated Hooper’s older brother before getting married. When Matt arrives in town, Ellen then pursues him, and an afternoon affair ensues. Afterward, Martin suspects the affair between Ellen and Matt.
Hooper’s fate
When Chief Brody, Hooper and local shark hunter Quint set out on Quint’s boat, the Orca, to hunt and kill the shark, tension builds among the three. Unlike with the film, in which Hooper and Brody become allies, the novel builds on the tension between the two. When Hooper descends into the water to fight the shark in a cage, it attacks Hooper by demolishing the cage and devours Hooper. Meanwhile, Brody — while horrified — senses relief with Hooper out of the picture. In the film, Hooper survives the attack and reunites with Brody as the credits are about to roll. The dark subplots of the affair and tension between Martin and Hooper would have made for a much different film — and likely not for the better.
Quint’s motivation
In the film, Quint’s speech about surviving the World War II USS Indianapolis disaster and subsequent shark attacks serves as a motivation for his hatred of sharks. There is no mention of Quint’s speech in the novel. This is a huge win by Spielberg and Co.
Quint’s fate
In the film, some might note the death of Christine Watkins in the film’s opening or the first true appearance of the shark — which prompts Brody’s famous line, “You’re gonna need a bigger boat” — as their favorite scenes. For others, it’s Quint’s unforgettable and gruesome death, as he’s swallowed by the shark, which has jumped out of the water and onto the stern of the Orca. In the novel, there is no such moment surrounding Quint’s death. After plunging a harpoon into the shark, the rope attached to the harpoon is tangled to Quint’s foot, and he is dragged into the ocean’s depths by the shark and drowns. Advantage: Spielberg and the filmmakers for their take on Quint’s demise.
