Question: Steven Spielberg's 1975 Shark thriller film featured what character, allegedly based on fisherman Frank Mungus?

Minority Report is a 2002 American neo-noir science fiction film directed by Steven Spielberg and loosely based on the short story of the same name by Philip K. Dick.  It is set primarily in Washington, D.C., and Northern Virginia in the year 2054, where "PreCrime", a specialized police department, apprehends criminals based on foreknowledge provided by three psychics called "precogs".  The cast includes Tom Cruise as Chief of PreCrime John Anderton, Colin Farrell as Department of Justice agent Danny Witwer, Samantha Morton as the senior precog Agatha, and Max von Sydow as Anderton's superior Lamar Burgess.  The film combines elements of tech noir, whodunit, thriller and science fiction genres, as well as a traditional chase film, as the main protagonist is accused of a crime he has not committed and becomes a fugitive.  Spielberg has characterized the story as "fifty percent character and fifty percent very complicated storytelling with layers and layers of murder mystery and plot".  The film's central theme is the question of free will versus determinism.  It examines whether free will can exist if the future is set and known in advance.  Other themes include the role of preventive government in protecting its citizenry, the role of media in a future state where technological advancements make its presence nearly boundless, the potential legality of an infallible prosecutor, and Spielberg's repeated theme of broken families. <SEP> Frank Mundus (October 21, 1925 – September 10, 2008) was a sport fisherman in Montauk, New York who is said to be the inspiration for the character Quint in the movie and book "Jaws".  Up until his death, he chartered out his boat "Cricket II" for those seeking the thrill of big game fishing. <SEP> Jaws is an American natural horror film series that started with a 1975 film that expanded into three sequels, a theme park ride, and other tie-in merchandise, based on a 1974 novel.  The main subject of the saga is a great white shark, and its attacks on people in specific areas of the United States.  The Brody family is featured in all of the films as the primary antithesis to the shark.  The original film was based on a novel written by Peter Benchley, which itself was inspired by the Jersey Shore shark attacks of 1916.  Benchley adapted his novel, along with help from Carl Gottlieb and Howard Sackler, into the 1975 film "Jaws", which was directed by Steven Spielberg.  Although Gottlieb went on to pen two of the three sequels, neither Benchley nor Spielberg returned to the film series in any capacity. <SEP>  In the story, a giant man-eating great white shark attacks beachgoers on Amity Island, a fictional New England summer resort town, prompting the local police chief to hunt it with the help of a marine biologist and a professional shark hunter.  The film stars Roy Scheider as police chief Martin Brody, Robert Shaw as shark hunter Quint, Richard Dreyfuss as oceanographer Matt Hooper, Murray Hamilton as Larry Vaughn, the mayor of Amity Island, and Lorraine Gary as Brody's wife, Ellen. Jaws is a 1975 American thriller film directed by Steven Spielberg and based on Peter Benchley's 1974 novel of the same name.  The screenplay is credited to both Benchley, who wrote the first drafts, and actor-writer Carl Gottlieb, who rewrote the script during principal photography.
