You can't go wrong with anything by Miike, and Suspiria is my fave Argento flick (the soundtrack and sets make it creepy even when nothing is happening).

'Inside (L'Interieur)' is getting some pretty good write-ups at the moment...might I suggest going over to Rue Morgue Magazine or Gomorrahy (excellent trailers section) and getting a feel for what's hot?

Personally, I want to check out some of these Japanese films like Machine Girl, Tokyo Gore Police and Oneechanbara...no doubt loopnode already has them!

I'm kind of surprised faceblaster didn't tip THIS MOVIE...not only is it shot on a porno set (If you've seen anything Billy Watson has shot, you'll probably get deja vu), but apparently Gia Paloma's in it too!
