An exploitation film is a film that tries to succeed financially by exploiting current trends, niche genres, or lurid content. Exploitation films are generally low-quality "B movies", though some set trends, attract critical attention, become historically important, and even gain a cult following.

A B movie, or B film, is a type of low-budget commercial motion picture. Originally, during the Golden Age of Hollywood, this term specifically referred to films meant to be shown as the lesser-known second half of a double feature, somewhat similar to B-sides in the world of recorded music. However, the production of such films as "second features" in the United States largely declined by the end of the 1950s. This shift was due to the rise of commercial television, which prompted film studio B movie production departments to transition into television film production divisions. These divisions continued to create content similar to B movies, albeit in the form of low-budget films and series.
