Bruce Brown, a filmmaker whose scrappy 1966 documentary "The Endless Summer" became an international phenomenon, introducing surfing to the world not as a frivolous fad but as a sacred search for the perfect wave, died Dec. 10 at a hospital in Santa Barbara, Calif. He was 80.

He had heart ailments and complications from a broken hip, said his son Dana Brown, also a documentarian.

Hailed as "the Bergman of the boards" and "the Fellini of the foam," Mr. Brown brought next to no professional training but an abundance of passion to his art form, which he used to popularize surfing far beyond the coastlines of California.

He had learned the sport growing up in Southern California before he hit his teens. At the time, surfing did not enjoy the reputation that it would acquire in later years — in large part thanks to "The Endless Summer" — as a refuge for pure seekers of the purest thrill.

Surfers had long been perceived as "silly and mindless," Matt Warshaw, creator of the Encyclopedia of Surfing, said in an interview. Contributing to that impression was Hollywood fare such as the "Gidget" films of the late 1950s and 1960s, featuring a parade of actresses as the quintessential beach bunny. Neither did "Beach Blanket Bingo" (1965), with Frankie Avalon and Annette Funicello, do much to help.

Mr. Brown began to experiment with film during his Navy service in Hawaii — a felicitous posting for a surfer — working with rudimentary equipment and improvised techniques. His first production, "Slippery When Wet" (1958), was for surfboard manufacturer Dale Velzy.

On its heels came five more surfing documentaries: "Surf Crazy" (1959), "Surfin' Shorts" and "Barefoot Adventure" (both 1960), "Surfing Hollow Days" (1961) and "Water-Logged" (1962).

They were low-budget affairs, featuring no soundtracks, and presented in theaters with Mr. Brown delivering live narration. Sometimes an as-yet unknown musical group, the Beach Boys, would play at intermission.

Mr. Brown burst to the fore with "The Endless Summer." The film featured two young surfers, Robert August and Mike Hynson, who embark in 1963 on a sojourn around the globe, hopscotching across the equator and back several times over, to follow the sun and chase the waves.

"It's kind of like a pipe dream," Mr. Brown said, according to the Orange County Register. "If you traveled around the world just right, you'd be in the middle of summer everywhere you went."

The trip took the surfers to Africa, Australia, New Zealand and Tahiti, among other locales, with Mr. Brown filming on a handheld 16mm camera and providing narration. The final product, film reviewer Stephen Holden later wrote in the New York Times, had the "perky ingenuousness of an early Beach Boys anthem."

Mr. Brown presented "The Endless Summer" in California before renting a theater during the winter in Wichita, where the movie was a blockbuster.

"We thought that would prove the film to the distributors in New York, and of course it didn't," he told the Times in 2002. "So we rented a theater in New York ourselves, hoping that the distributors would drive by the theater and see the crowd, which they did. It was the surfer guys against the New York establishment."

"The Endless Summer," whose budget had been $50,000, became a sensation. It grossed $30 million, making it one of the most commercially successful documentaries in film history.

"What it did was show the world the idyllic lifestyle that still resonates with people to this day, even though surfing as a sport has progressed," said Barry Haun, curator and creative director of the Surfing Heritage and Culture Center in San Clemente, Calif. "You don't have to be a surfer to watch this and enjoy it. I think anybody who watches it wishes they surfed, if they don't already."

Bruce Alan Brown was born in San Francisco on Dec. 1, 1937. His mother was a schoolteacher, and his father owned a small toy store chain. He grew up in Long Beach, where, according to surfing writer Drew Kampion, he said he "majored in not going to school."

After his Navy discharge, he was working as a lifeguard when Velzy offered him $5,000 to make "Slippery When Wet."

He made few films after "The Endless Summer," in part because he found it difficult to tear himself away from surfing. "I didn't want to go to Hollywood," Mr. Brown told the Los Angeles Times. "I'd rather live in a [trailer] on a perfect surf break than live in Beverly Hills in a mansion with 50 servants and Rolls-Royces."

The most notable of his subsequent films was "On Any Sunday" (1971), a documentary about motorcycle racing that featured movie star and motorbike enthusiast Steve McQueen and that was nominated for an Academy Award. Mr. Brown also made a sequel to his seminal film, "The Endless Summer II" (1994), with his son.

Mr. Brown's wife of 46 years, the former Patricia Hunter, died in 2006. In addition to Dana Brown, of Los Angeles, survivors include two other children, Wade Brown and Nancie Brown, both of Gaviota, Calif.; eight grandchildren; and two great-grandchildren.

For all the drama and beauty that his surfing documentaries captured, there was something that Mr. Brown said he could not catch on film.

"The thing you can't show is the fantastic speed and that feeling you get in the pit of your stomach," he said in "The Endless Summer," filming a wave at Cape St. Francis in South Africa. "I couldn't help but think of the hundreds of years these waves must have been breaking here. . . . Think of the thousands of waves that went to waste, and the waves that are going to waste right now."
