The Best Buy version of the Cloverfield DVD included a 30 minute "TJ Miller's ("HUD") Video Diary", featuring behind-the-scenes video of TJ Miller doing what he does best, goofing around on the set of Cloverfield. If you haven't already purchased the limited-edition version, it is probably too late, but you can still watch the videos here.
