Here's some stuff I'm eager to watch. Not Lindy Hop specifically, but all pretty cool. There's a common thread to these films. Two are more obvious than the third. They bring to mind Jimmy Valentine.
Wheelchair Dance Competition
En Tus Brazos
Love 'N Dancing - Trailer
I just picked this up on DVD. It looks like you can watch in YouTube for $3.99. Fun stuff.
Don't know who these folks are, but fun stuff and actual lindy hop.
