You know, from watching this, I think the slow motion would be way more effective if it was single-framed - and with a motion that can't easily be mistaken for the character intentionally moving very slowly.

You can rise from your leg slowly, but you can't fall slowly. Your jacket can't flap slowly. Your hair can't fall slowly.

As for why I suggested single frame, it's to emulate the extreme difference in fluidity of motion we see when we look at extreme, 600 frames per second or so slow motion.
Check out the movie: 300. Check out its sequel. :P
