The film cost $50,000 to produce, according to various contemporary sources including the 12 Jun 1966 NYT. It was self-financed by filmmaker Bruce Brown, a surfer who had spent the last ten years documenting the sport on film. Locations included Newport Beach and Malibu, CA, the Banzai Pipeline off the north shore of Oahu, HI, and the following international locations: Ghana; Nigeria; Cape St. Francis, South Africa; Tahiti; Australia; and New Zealand. According to an article in the 12 Jun 1966 NYT, Brown often hitchhiked to filming sites, toting his 16mm camera, with featured surfers Mike Hynson and Robert August, and their surfboards. According to a review in the 20 Jun 1966 DV, the documentary took two years to produce.
       The film, shot in 16mm, was blown up to 35mm for exhibition. Brown organized independent screenings as early as Jun 1964, when an Associated Press article printed in the 26 Jun 1964 [Baytown, TX] Baytown Sun announced the world premiere had occurred that week at the Encore Theatre in Hollywood, CA. The following month, a 27 Jul 1964 LAT brief listed two showings that night at the Fox Theater in Venice, CA. On 5 Feb 1965, LAT listed screenings the next two nights at the Pasadena Civic Auditorium, and the 7 Jul 1965 LAT later announced the “final California showings” of The Endless Summer beginning that night at the Santa Monica Civic Auditorium. Screenings at Laguna Beach High School were also scheduled to take place 21-24 Jul 1965. Regional screenings continued, with Brown traveling from city to city to exhibit the film, himself. The Endless Summer broke records in Wichita, KS, where it opened in Feb 1966, as noted several months later in the 25 Aug 1966 LAT. The box-office success in Wichita prompted Brown to seek national distribution. However, he was unable to interest New York-based distributors, who reportedly dismissed the “‘home movie’ about surfing.” At great financial risk to himself, Brown invested another $50,000 to lease the Kips Bay Theater in Manhattan, the 12 Jun 1966 NYT noted. The 15 Jun 1966 premiere at Kips Bay was sponsored by New York’s Special Events Commissioner, John “Bud” Palmer, according to the 20 Jun 1966 DV. Seven months later, an article in the 25 Jan 1967 [Dover, OH] Daily Reporter noted that The Endless Summer was still playing at Kips Bay, and had recently “placed No. 10 on Variety’s weekly list of the country’s money-making films.” The 8 Feb 1967 Var stated that the film was about to set a new record in Washington, D.C., for “having the longest run and highest gross” in the area, after grossing over $150,000 at the “tiny” Janus One and Janus Two theaters.
       A 17 Aug 1966 Var brief reported that, after the Kips Bay opening, New York-based distributor Cinema V acquired national distribution rights.
       Assistant photographer R. Paul Allen was credited with shooting the Malibu sequences in the 25 Aug 1966 LAT.
       The Endless Summer was added to the Library of Congress’s National Film Registry in 2002. In the meantime, Bruce Brown produced a sequel, The Endless Summer II (1994, see entry), which was co-written by his daughter, Dana Brown. Continuing in her father’s footsteps, Dana Brown directed the 2003 surf documentary, Step Into Liquid (see entry).
