We're still more than a month shy of the Back to the Future 25th Anniversary Trilogy pack shipping on Blu-ray, but if you just can't wait HighDefDiscNews points out a few snippets of special features Universal's posted on YouTube. Check out the videos (embedded after the break) for a couple minutes of making-of talk from the director and producer, a clip focusing on Christopher Lloyd's performance and (spoiler alert!) the scene where George McFly punches out Biff in the first movie. Unfortunately the clips are only in 480p here, but that does leave us with something to wait a few more weeks for.
