Warner Bros has been trying some pretty cool, experimental stuff with their first BD Live movie, The Dark Knight. And now, that list includes watching the movie with Christopher Nolan.
I don't claim to think that I can in any way influence your purchase of The Dark Knight on Blu-ray ($24) or DVD ($15/$21). In fact, I don't really want to. I couldn't care less if you buy it, rent it or stomp any loose copies you spot at the store.
