I don't know what you call them really, fan videos, I suppose, that youtube sub-genre of people editing clips from favourite films to music or giving favourite songs a new video. Most of them are uploaded just to show the person loves this film/song, which is fair enough, but some are genuine attempts to create something fresh, to capture the essence of the story or lyrics.
Here are two of my favourites; the first from RubyTuesday717 who has managed to find music capable of doing justice to what is, arguably, the most profoundly heartbreaking film ever made, Eternal Sunshine of the Spotless Mind.
And this from Captainmcglue, finding metaphorical riches in the lush romanticism of Richard Hawley's Open Up Your Door. Enjoy!
