This video is a montage of people dancing from 73 different Hollywood films!  Not only is it entertaining to watch, but I promise you'll find yourself trying to figure out what movies each scene if from!

I know there are scenes from "The Mask" "Dirty Dancing" "Grease" "Chicago" and "Revenge of the Nerds" - see if you can help me name some more.  Maybe together we can name all 73!
