There's one REALLY good movie everyone should check out, My friend kevin (Mr. Morbid) got it from a guy in this band called The Meat Shits and it's called The Iron Man, It's about an hour to 1hr-30mins long, It's a Japanese movie in black & white but it's about this guy who's got a "fetish" for metal.. He rips open his leg and sticks a peice of metal in it and sews himself back up, But the metal from what I can remember is some kind of sacred steel or something, So he becomes this evil huge robot type thing and he transforms every day. it's really gory I have to say. I didn't think I would like it at all, even before he was telling me how good it was and I thought naw.. But after watching it atleast 5 times on an old generation VHS tape it was really amazing. Here is a page about it.

You can get it on DVD now, I watched a Japanese uncut Laserdisc recorded on VHS back in the day. It's worth checking out.
