idk, i think most of them stand alone pretty well whether or not you know the film. just look at goat stare, one of the biggest tunes in dubstep and im willing to bet a substantial amount of people have never seen scanners
i mean nowadays its become a bit more of a faux pas (most likely due to brostep in particular and the extremely heavy use of corny samples before drops), but dubstep in general was BUILT on movie samples. like the amount of tracks that sample blade runner alone is pretty overwhelming
