Trivia: Jaws was originally rated R, but after some bloody scenes were trimmed down, it received a PG rating. The PG-13 rating was created in 1984, nine years later.
Trivia: When Brody is flicking through the shark book he sees a photo of a shark with a diver's air tank in its mouth, this is how he kills the shark later. (00:25:25)
Trivia: Steven Spielberg reshot the scene in which Hooper discovers the head of local fisherman Ben Gardner not in Martha's Vineyard, where the rest of the movie was filmed, but in editor Verna Fields' swimming pool. Spielberg spent $3,000 out of his own money because Universal refused to foot the bill for any more shooting.
Trivia: Although you cannot see him, Steven Spielberg is actually one of the people at the beach bonfire playing a clarinet.
Trivia: Alex Kintner owns a seafood restaurant now and even has a sandwich called the Alex Kintner Sandwich.
Trivia: According to Spielberg, of the 12 hours of filming schedule each day, only 4 hours were spent actually filming. This was due to difficulties with the shark prop, disagreements with the actors, unwanted civilian boats coming into view and poor conditions at sea.
Trivia: Many problems happened at sea involving the boats. The Orca, for instance, once began to sink with the actors on board, and in another case, Carl Gottlieb, the writer of the film, was nearly killed in an accident when he nearly hit the propellers of the crew boat.
Trivia: When the shark's first victim's hand is found in the sand, Steven Spielberg believed that the fake arm they used was too false, so instead they buried a female crew member in the sand with her hand sticking out.
Trivia: The marine biologist, Hooper, was an unlikable character in Peter Benchley's novel. In the book, Hooper had an affair with Chief Brody's wife, and Hooper was appropriately eaten alive by the Great White at the end. Steven Spielberg originally intended to follow the Benchley novel and allow Hooper to be eaten inside the shark cage. As it happened, Spielberg fell in love with some accidental footage of a real Great White thrashing wildly with an empty shark cage; in fact, he loved that shot so much, the scene was rewritten on-the-fly to allow Hooper to escape the cage and survive.
Trivia: The script was not written in one go. The writers had dinner with Spielberg and the cast every night, listened for suggestions for tomorrows shoot, and then finish their script a bit before shooting.
Trivia: The reason that there are many shots of only the dorsal fin is because the prop shark was so damaged, they removed the fin and placed it in the water to make it look like the shark was swimming just below the surface.
Trivia: Because Spielberg took production over 100 days and made the crew suffer for his attention to detail, he refused to come for the final day of shooting, believing the crew were going to throw him into the water after they had finished. It has since become a custom of Spielberg to be absent on the final day of shooting on the majority of his films.
Trivia: In the film, the Mayor is acting out of his concern for the town and its people, fearing an economic collapse if summer is ruined for beachgoers. In Peter Benchley's novel, things are a bit more complicated as the Mayor owes and is being manipulated/extorted by the mob due to their grip on Amity in general and money owed for a loan he took out to help save his then-ailing-and unaware-wife.
Trivia: Perhaps the most often-repeated "Jaws" trivia is that actor Roy Scheider spontaneously ad-libbed the film's most iconic line, "You're gonna need a bigger boat!" Screenwriter Carl Gottleib apparently started this rumor after "Jaws" became a worldwide sensation in 1975, probably because the only thing that generated as much publicity as the film itself was backstory of the film's production; and Gottleib's rumor has charmed fans and persisted to this day. However, when reporter Paul Iorio interviewed Roy Scheider in 2000 (for a story in the San Francisco Chronicle on the occasion of the "Jaws" 25th anniversary), he specifically asked Scheider about the line "You're gonna need a bigger boat." Scheider answered: "That was in the script. The first time he [Chief Brody] sees the shark. But I liked the line so much, it amused me so much, that I said, 'I bet I could work this in a few other places.' So I worked it in two more times." Indeed, Chief Brody does refer to needing a bigger boat twice more, and those subsequent lines are ad-libbed; but the very first and most memorable time he says the line, it was purely scripted. Paul Iorio's question and Roy Scheider's answer were edited out of the published San Francisco Chronicle story.
