The following movies are generally grouped in the genre of "Psychedelic Cinema"; a period which represented the effects of various drugs (not just the psychedelic ones) within the international filmmaking community at large.
In my personal view this genre is notably 1) episodic, 2) comedic and 3) subversive. Films such as Dr. Strangelove, Zabriskie Point, Joe and Easy Rider are often included in the grouping, however I believe the downbeat nature of these works should be considered in a genre of their own: BUMMER Cinema (see below) – my own term that I'm attempting to memeticise here.
List of films (incomplete):
Films about psychedelic drug use are also included sometimes within the genre, but I think this may be taxonomically incorrect.
Although this is still in the first person, feel free to add and mutate this page as you see fit.
