TORn message board member Beutlin alerts us to a German film website Moviepilot.de that has recently posted a video showcasing Hobbiton and a couple of WETA artists working on The Hobbit.
Most of the video is in German, but much of the relevant bits (from 07:10 through to around 13:00) are spoken in English by New Zealanders.
The topic is already being discussed on our message boards, and anyone willing to send in an English translation of the relevant bits is most welcome to do so.
UPDATE: TORn message board member mona2505 has obliged us with an English transcript of the video. The same can be found here.
