And it's "This is not a boat accident!", not "This was no boating accident!"
Creator Backlash: During interviews later in his career, Peter Benchley claimed he came to regret writing the original novel when he learned that the worldwide fear of sharks he felt his book and the film version created had led to massive shark overfishing that was driving several species close to extinction. He became a vocal ocean conservation activist to make up for it, and remained so until his death. His later book The Beast even features the hero ranting in his head about how much damage the film has done.
Defictionalization: In 2010 when the Egyptian resort of Sharm El Sheik experienced killer shark attacks it pretty much used the plot of Jaws as its guide, including denying the problem, resisting closing the beaches, reluctantly closing them after a near shore attack, killing the wrong shark and declaring it the right one despite clear evidence to the contrary, re-opening the beaches with a fanfare declaring them safe, then having more attacks take place. After that the shark simply left of its own accord, perhaps it was Genre Savvy enough to know what came next in film.
Enforced Method Acting: Initially, they weren't getting the reaction shot Spielberg wanted from Susan Backlinie when the shark first grabs Chrissie, so they did a take where they didn't tell her when it was going to happen. That's the take that went into the movie.
Fan Nickname: Due to the first shark's Production Nickname, the later sharks are usually called "Bruce (sequel number)" or something along those lines. The baby shark in the third movie also tends to be called Bruce Jr. to distinguish it from its parent.
Old Shame: The movie's popularity turned the book into this for Peter Benchley. The movie set off a wave of paranoia about going to the beach as well as a renewed spate of shark-hunting that drove various species almost to the point of extinction. Benchley lamented that he would never have written the book had he actually known anything about sharks and that they weren't like the monster about which he had written.
Production Nickname: Bruce for the first shark. Spielberg himself called it Great White Turd due to its breakdowns.
The Red Stapler: Inverted. Beach attendance dropped significantly after this movie.
Science Marches On: Much more has been learned about shark behavior since 1975. As a consequence, most of the theories Hooper voices, believed to be valid at the time, have since been disproven.
There were problems with getting the mechanical shark to work, forcing the creators to turn it into mostly The Unseen.
In fact, Quint's Indianapolis speech was only recorded because the crew was waiting around for "Bruce" to be repaired, so Spielberg added more dialogue to keep from wasting so much shooting-time. It wound up being the dramatic high point of the film.
Also, Hooper was Spared by the Adaptation because when shooting scenes with actual sharks in Australia, there was that great take of the shark rolling on top of an shark cage - but it was empty (the stuntman had fled for his life).
"You're gonna need a bigger boat." AFI's #35 choice on its "Quotes" list.
Also, the shooting star as Brody loads his revolver on the boat.
The footage of the Shark rolling on top of the shark cage wasn't planned, but was far too awesome not to use. And is why Hooper ended up surviving.
Troubled Production: An unusual case; it seems that the more troubled the production of each film was, the better it turned out. The original film barely even got made at all due to the numerous troubles they had with the weather and the mechanical shark, yet is easily the best of the series. The second had a massively problematic start, but things eventually smoothed out during filming, and it ended up a decent film. The third's production problems were mostly limited to the challenges of working in 3-D, and the resulting film was... pretty bad. The Revenge had the smoothest production of all the Jaws films by far — and yet it ended up the absolute worst film.
Executive Veto: When Halloween Horror Nights returned to the Studios park in 2006, the ride's skippers put together their own script that was more profane and violence-based that they hoped they would be able to use during the event nights. When the employees presented the script to the resort's higher-ups, they rejected it and forced them to stick to the regular script for reasons unknown.
Throw It In: The skipper sometimes will make a slight change to their spiel to poke fun at the reactions of the riders, and there are situations where the skipper will be forced to due some improvising, such as if they accidentally drop the grenade launcher into the water. note Yes, it actually has happened before.
Troubled Production: A rather serious case, as the ride was essentially non-functional when it first opened. It had to be completely shut down and reworked entirely, and it took three years for the ride to finally be opened up again. Universal even sued the people who manufactured the original version of the ride.
