Will it be on DVD?

It is out on DVD but there is no special features on the disc, which is a shame because I would have liked to have seen how it was made.

It's censored in the U.S. You can't legally buy it there (unless you hack your DVD player and import it, but hacking your player is also illegal). They won't even let National Geographic show it anymore.

Of course, if you're an American, you won't know any of that.
