Big ol', happy ol' Al Roker of America's The Today Show went on set of The Dark Knight recently and you can see the video care of Youtube either below or here{
This being The Today Show, a kind of US equivalent of This Morning with more handwaving and less Fern Britten, this is really beginners' stuff (Roker gives the impression of having no clue what happened in the first movie), but we do get interview snippets with Christian Bale, Christopher Nolan and Aaron Eckhart, plus a few clips of shooting, although we don't think there was any new finished footage there.
Heath Ledger doesn't show up. But you know where he does show up? The new issue of Empire. Which is on sale now. Wow, that was seamless.
