Another one I've talked about repeatedly: Tokyo Gore Police (
http://www.imdb.com/title/tt1183732/). Another very fun movie but incredibly graphic - not for the kiddies! I'll grant you it's all fake (a couple steps above Troma IMO), but still pretty wild - I'd call it Evil Dead/Evil Aliens level gore - but then Evil Dead didn't have a guy getting his dick bitten off and growing a cannon to replace it....Evil Aliens is a little closer ;p (maybe Undead as well - need to watch that one again too).
This is a clip from the middle - interesting visit to a truly messed up fetish club. Again, I highly recommend checking out the DVD on netflix (or even xbox live movies) - or just buying it. I haven't even ripped the excellent scenes with a quad amputee with samurai swords or machine guns for limbs or the school girl squirting acid from her breasts and melting another cop.

BTW, any feedback on these - quality, etc - is appreciated (I already mentioned the subs issue).
