There's a version that's already available through
Amazon that's definitely region free. (I thought I posted about the DVD in here, but I've just recalled that it was in a thread about Wavesong. ::) ... It made sense in context. |:|)
I'm sorry I didn't post about it in this thread! :-/ The DVD available on Amazon is definitely region free - I have a copy. (I for one AM that obsessed. :P) It has two commentaries (one normal, and one a musical!) and a few bonus features. Both commentaries include the cast and creators, including the stars. The DVD also has a few Easter Eggs. I have to say, I did enjoy the extras. The commentaries were both fun - especially Commentary! the musical - and there were some great lines. I loved about half the songs in the musical commentary, so it's not quite on the same level as the show itself, but it's a brilliant idea, and they carried it off well.
The extra features include three features ("The Movie", "The Music", and "What Just Happened" (which was about the fans' reactions and such)), plus a video of Evil League of Evil Application Videos. The three combined featurettes are about 20 minutes long, and the first two are especially enjoyable. One of my favourite quotes: "How do you stomp around like you’re 2,000 pounds, in the span of two and half seconds, singing like a chipmunk? I still don’t know." - NPH
The Aussie dollar's really good at the moment (comparatively :P), so it would be around $25 (including postage), which is a bit expensive for how short it is, but my theory is if you're going to be watching it a lot, it's not so bad, which is why I bought it. ;P
