A similar idea is behind "Matrix" and
"The 13th Floor", but
Fassbinder's version is indeed a classic and impressive one.
13th Floor is drawn from the same story -- that's how I heard of it.
It was pretty thrilling to learn that the story was filmed over _25_
years earlier! That's 1973 folks. Since it's impossible to find,
PAL is no drawback. Thanks for responding.
