The guys at Auralnauts realize that a movie's score changes everything about what you're seeing onscreen.  Especially if that score was composed by John WIlliams.

But what would happen if you stripped out all that music?  Things suddenly get a little weird.

The problem is that if you strip out the soundtrack, you lose the voices, too.  And that leads to the funniest part of this video:  Someone had to go in and make a new voice for Chewbacca.

My Lord, even if you only watch it for the first 0:37, it's worth it.
