The punk subculture has either spawned or inspired films, and even the film genre of No Wave Cinema. These films range from coming of age dramas to teen comedies, documentaries and even avant-garde cinema. Hence defining "punk film" as a genre is difficult due to the vague nature of the term. These are films that either came from the punk subculture, were inspired by, or share themes common to it. For example, some of these films were made using the DIY ethic.
