There are already a few Albert Pyun flicks lined up for B Movie Night reviews, and I’ll be adding more as I find them. He has made a lot of low-to-no budget and straight-to-video flicks of varying levels of quality and coherence. io9 has an interview with him.
[The decision to make post-apocalyptic films] was the direct result of the fact that locations that weren’t in ruins were more expensive. Locations that were in ruins or demolished or some kind of big forest fire had happened, were much easier to get. And they didn’t care as much how you left it. So that was mainly the reason why a lot of us gravitated towards that genre.
