Today, Back To The Future makes a welcome return to cinemas to celebrate its 25th anniversary, and in celebration we've got a little featurette giving you the background to the movie's famous Johnny Be Good performance, which should provide some news even to die-hard fans.
This snippet includes behind-the-scenes footage of Michael J. Fox shredding the Chuck Berry classic on guitar, and proves just how good he actually was with the guitar. And who doesn't love the sight of someone playing guitar behind his head just for effect?
This clip comes from the Blu-ray release of all three Back To The Future films, due on October 25, but the cinema release should keep you going in the meantime. If you're hungry for more, however, Shortlist has another clip - this one focused on Christopher Lloyd's Doc Brown - and we've got an oral history of the films from director Robert Zemeckis and executive producer Steven Spielberg right this way.
