This movie was released in 70mm blow up and had a six track mix. Produced by Gary Kurtz. One of the biggest flops in the history of the movies, even for a low budget flick its considered a disaster.
Basically tries to tell the same story according to critics as blade runner and blade runner did it better.
As for what darkgryphon had to say the 5.1 could be authentic if it was a remix of the six track and not a cooked up 5.1 from a stereo source like a lot of bargain basement dvds.
