common characteristics of experimental films:
radical filmmaking techniques
non diegetic (no storyline/linear structure)
blatant disregard for the cinematic status quo
random-doesn't necessarily make sense to the audience, however generally sticks to a theme
contrast within the image/sound
rules are made up by the filmmaker, don't conform to standard mainstream film conventions
rapid editing
minimal dialogue
choppy editing
irrational, non-contextual arrangement of images
out of focus
non diegetic/no music/instrumental
black and white/old fashioned looking
rhythmic-timing is important-sound fits in with image
repetitive
abstract shapes-also timed according to the music
mirrored images/shadows
very loud non diegetic sound e.g. annoying piano (sets the audience in a trance like state)
limited/no dialogue
