Think you know 'Jaws'? Test your knowledge with this trivia ahead of the movie's 50th anniversary

Friday marks the 50th anniversary of ''Jaws.'' It remains one of the most beloved and rewatched movies of all time. But how good is your knowledge of the some of lore surrounding Steven Spielberg's 1975 masterpiece?

Read on and see how much you know about ''Jaws.''

What was the nickname given to the shark?

Spielberg named his mechanical shark ''Bruce,'' after his attorney, Bruce Ramer.

Where did the title come from?

When author Peter Benchley's 1974 book was going to print, he needed to choose a title. He has juggled various titles — ''Leviathan Rising,'' ''Silent Fall'' — before, at the last minute, choosing ''Jaws.'' What did it mean? Benchley, himself, wasn't sure, he told his editor, but it was short.

What's the origin of the iconic movie poster?

The image of the rising shark came from the cover of the novel's paperback edition, illustrated by Roger Kastel. For his painting, Kastel went to the American Museum of Natural History to photograph a great white shark from a diorama that was laying on an easel.

What was the inspiration for Amity?

Though Spielberg shot ''Jaws'' on Martha's Vineyard, off Cape Cod, it was the neighboring island, Nantucket, that inspired Benchley's novel. He has spent time fishing there with his father. In the book, the fictional Amity is on the south shore of Long Island.

Who was first attached to direct ''Jaws''?

Dick Richards was initially in line to direct the film, but producer Richard D. Zanuck said he lost the job after, in a meeting, repeatedly referring to the shark as a whale.

How old was Spielberg when he began the project?

26.

Who sought but was turned down the role of Brody?

Charlton Heston wanted to play the Amity Island police chief, but Spielberg instead cast Roy Scheider.

What's the name of Quint's boat?

The Orca. Not coincidentally, two years after the massive success of ''Jaws,'' a 1977 ripoff about a killer whale was released titled ''Orca.''

What led to the shark often malfunctioning?

Salt water. The shark, built by special effects artist Bob Mattey, would get corroded by the salt water of the Atlantic Ocean, leaving it unusable for times – particularly early in the filmmaking. Spielberg pivoted and instead doesn't show the shark until well into the film, an approach that ultimately led to a far more suspenseful film. Spielberg once estimated that Bruce's mechanical delays added $175 million to the movie's box office.

How long into ''Jaws'' does the shark fully appear on screen?

It's not until one hour and 21 minutes into the movie that we really see the shark.

Was the movie's most iconic line scripted?

No, Schieder adlibbed ''You're gonna need a bigger boat.'' Screenwriter Carl Gottlieb, though, has said the line had been percolating on set. The size of the barge carrying equipment and craft services was often slighted by the crew who felt producers weren't spending enough. Gottlieb told The Hollywood Reporter in 2016: ''It became a catchphrase for any time anything went wrong – if lunch was late or the swells were rocking the camera, someone would say, ‘You're gonna need a bigger boat.'''

What disaster was Quint a survivor of?

The sinking of the USS Indianapolis, the U.S. Navy cruiser torpedoed by a Japanese submarine during World War II. Quint's lengthy and memorably speech in the film wasn't in the novel but was, according to Spielberg, penned by the uncredited screenwriter John Milius. Spielberg wanted a backstory to why Quint hated sharks so much. Though debate has continued over the years over who wrote the monologue, everyone has agreed Shaw synthesized it, and deserves most of the credit for the scene's power.

Does Spielberg appear in ''Jaws?''

The director isn't seen in the film but his voice is heard. During the finale of the film when Quint is readying the harpoon, it's Spielberg's voice on the radio. He says: ''This is Amity point light-station to Orca. Orca, come in.'' Spielberg shows up in a couple other ways, too. A clarinetist in high school, he plays briefly on Williams' score. And Brody's dogs were Spielberg's cocker spaniels, Elmer and Zalman. (For his part, Benchley makes a cameo as a TV reporter during the July 4th beach scene.)

How far over schedule did ''Jaws'' run?

The production was scheduled for 55 days but took 159 days to complete. The budget also nearly tripled, to $9 million, plus $3 million more in post-production. Though ''Jaws'' become the prototype summer movie, it was originally expected to open around Christmastime the year before.

What was ''Jaws'' rated?

Though it caused some controversy, the Motion Picture Association of America gave ''Jaws'' a ''PG'' rating. At the time, there was no PG-13 rating. (That only began in 1984, with ''Indiana Jones and the Temple of Doom,'' after a handful of other Spielberg productions, including ''Raiders of the Lost Ark'' and ''Gremlins'' led to the new category.) Jack Valenti, then-president of the MPAA, defended the rating by arguing that ''‘Jaws' involved nature's violence, rather than man's violence against man,'' Valenti said. ''This is the same kind of violence as in ‘Hansel and Gretel.' Children might imitate other kinds of violence, but not the kind seen in ‘Jaws.'''

The movie's poster carried the warning: ''MAY BE TOO INTENSE FOR YOUNGER CHILDREN.''

What did ''Jaws'' lose best picture to at the Academy Awards?

''Jaws'' was nominated for four Oscars and won three: best sound, best editing and best score for John Williams. The competition for best picture, though, was fierce. The nominees, alongside ''Jaws,'' where ''Dog Day Afternoon,'' ''Barry Lyndon,'' ''One Flew Over the Cuckoo's Nest'' and ''Nashville.'' The winner was ''One Flew Over the Cuckoo's Nest.''
