Beach Party film

Beach party movies were an American subgenre of feature films produced and released between 1963 and 1968, created by American International Pictures (AIP), beginning with their surprise hit, Beach Party in July 1963. With this film, AIP is credited with creating the genre. In addition to the AIP films, several contributions to the genre were produced and released by major and independent studios alike. According to various sources, the genre comprises over 30 films, with the lower-budget AIP films being the most profitable.

Generally comedies, the core elements of the AIP films consisted of a group of teenage and/or college-age characters as heroes; non-parental adult characters as villains and/or comic relief; simple, silly storylines that avoided any sober social consciousness; teen trends and interests (such as dancing, surfing, drag racing, custom cars, etc.); simple romantic arcs, original songs (presented in both the “Musical” genre style and as ”source music”); teen-oriented musical acts (frequently performing as themselves); and a tongue-in-cheek attitude toward the target audience.

The earliest films by AIP, as well as those by other studios, focused on surfing and beach culture. Although the genre is termed "beach party film", several subsequent films that appeared later in the genre, while keeping most of the core elements mentioned above, do not actually include surfing—or even scenes on a beach.

One of the earliest uses of the term in print is found several times in the June 1965 issue of Mad magazine in an article written by Larry Siegel. Commentators on the genre have used this term as well. The term "beach party film" is distinguished from a “surf film” or “surf movie” in that the former refers to the comedies of the 1960s, whereas the latter terms refer to surf documentaries (such as The Endless Summer or Riding Giants), a still-active genre. Occasionally the term “surf movie” refers to a straightforward dramatic film that uses surfing as a backdrop or plot device, such as Big Wednesday or Blue Crush.
