I truly hope you get to watch this film. Yes, one can't discuss Wiseman intelligently without mentioning the term "reality fiction." (It's also worth noting that Wiseman regards documentary as another form of fiction and has considered his oeuvre as one long film [a great one, I'd add].) The understanding of its anatomy makes Mller's association all the more ingenious.

I believe it was partially financed by an American network. A friend of mine told me that ARTE, which I'm sure you're familiar with, was also involved, but I've yet to confirm that. Unfortunately, and contrary to popular belief, the growing mainstream visibility of documentaries since the late 90s has had no bearing as far as Wiseman's work is considered. He still has to scratch and claw in order to get the financing together, and has gathered enough friends over the years who make sure that his work is seen by a small, sophisticated audience. But, hopefully, now that his films can be obtained affordably, one could discuss them without any risk of sounding esoteric.
