Perfect Unison

The best supercuts are those that contain a wide-ranging variety of clips that have something unexpected in common, masterfully edited into a coherent theme with catchy music. Filmmaker Jon Lefkovitz has all that in this compilation of clips from film and TV of characters (they're not all people) moving in unison. You might think it would be dominated by choreographed dance numbers, and it has some, but most of these clips just illustrate two characters that are very much in tune with each other. There's a list of the movies and TV shows used at the YouTube page. The music is "Second Song" by TV on the radio. (via Laughing Squid)
