I guess the US disc that just came out is the way to see it. Just keep in mind it is a very poor disc that was "authored" using a pioneer table recorder instead of a proper authoring software. the picture quality is not bad at all (it is a digital video feature anyway) although that is not enough to warrant a purchase of $25.... I will buy it as soon as I manage to find it for cheap- or free LOL
I wish the movie itself was better- I have only viewed it via the Italian DVD and it had some entertaining moments but the rest was pretty bad. Look out for the stolen footage from ARMY OF DARKNESS!

If you want to see a great post-2000 movie by Mattei, look no further than LAND OF DEATH aka CANNIBAL HOLOCAUST: CANNIBAL VS. COMMANDO- CH and PREDATOR (or perhaps ROBOWAR?) combined in one!
Mattei always did better in action (STRIKE COMMANDO, ROBOWAR) and exploitation (WOMEN'S CAMP 119, BLADE VIOLENT)- horror never seemed to be his kind. I recommend these 4 films highly. Go out of your way to track them down and enjoy them with your mates and tons of beer
