La métamorphose du papillon

La metamorphose du papillon is a slight but reasonably well-performed short film from Gaston Velle, one of the less revered of the early French filmmakers. I think the idea was that the viewer was supposed to be fooled into thinking he was watching a real caterpillar changing into a chrysalis. Of course, we aren't really watching a tiny caterpillar on a leaf, but an actor or actress writhing about in a sort of sleeping bag on a giant prop. (imdb)
