It has been five decades since Steven Spielberg’s “Jaws” made epic waves when it hit theaters, breaking box office records and transforming the movie industry as the first summer blockbuster of its time. Beachgoers were afraid to go into the water.

To celebrate the film’s June 20, 1975, release, a National Geographic documentary promises to take viewers on a 90-minute “ultimate deep dive” into what it took to bring the Oscar-winning cult shark thriller to life.

“Jaws @ 50: The Definitive Inside Story” will debut on the National Geographic channel on July 10 before making a splash on Disney+ and Hulu the next day.

“You may think you know the full story of ‘Jaws’—but not until now,” a May 30 statement reads.

The documentary explores the inception of “Jaws,” based on Peter Benchley’s 1974 novel of the same name, and how the film “continues to ripple through pop culture, cinema, and shark conversation to this day.”

Set in the fictional New England town of Amity Island, the film centers on a man-eating shark terrorizing the region as Police Chief Martin Brody, played by Roy Scheider, joins forces with marine biologist Matt Hooper (Richard Dreyfuss), and shark fisherman Quint (Robert Shaw), to hunt down the massive fish.

“Jaws @ 50” was directed by Laurent Bouzereau and made in partnership with Wendy Benchley, the author’s widow.

The project features interviews with several leading Hollywood figures, including actress Emily Blunt and filmmakers James Cameron, George Lucas, and Guillermo del Toro, as well as some of the original cast and crew of “Jaws,” among them Lorraine Gary, who played Ellen Brody, opposite Scheider.

Viewers can also expect never-before-seen footage from Spielberg’s personal archive, as the director reflects on the lasting legacy of his film.

“Making ‘Jaws’ was a life-altering experience,” Spielberg says in the documentary’s trailer.

The filmmaker, who is also famed for directing “E.T. the Extra-Terrestrial” (1982) and “Schindler’s List” (1993), detailed some setbacks he faced while filming “Jaws,” including the film’s production being more than three months behind schedule.

“And 80 percent of the time, the shark didn’t work,” he said, referring to the mechanical prop shark created to play the titular great white on the big screen.

“When the film wrapped, I had a full-blown panic attack. But the success was fantastic,” Spielberg says.

“The film that I thought would end my career is the film that began it.”
