At this point, there isn't much that hasn't already been said about Michael Jackson's Thriller. Upon its release in 1982, the album was the smashiest of smash hits, spawning seven top-10 singles... oh, and it's the best-selling album of all-time. Let's just move on.
The point here is, anybody with access to a TV or the Internet has likely seen the classic video to Jackson's "Thriller" single, which resurfaces every year around Halloween. The choreography and horror-glam costumes reinvented the music video genre, but countless hours went into the final masterpiece. This video captures some of that hard work.
