DVD releases of Andrzej Zulawski's movies are a bit like those jokes about PCs, 10 minutes after they're released they are out of date, or in Zulawski's case, out of print.
A couple of days ago I found out that a company called Mondo Vision were releasing another one of his movies so I went to check out their website and lo and behold, they seem to have the rights to most of his interesting work, and by interesting I mean the things I'm interested in seeing.
The only real problem is that since this is a niche company and they seem to be going all out on the DVDs, the prices get a bit high (both movies are $26.99 on Amazon).
