Most Brutal movie ever made in terms of violence?

[-Skeme-]

I'm 100% sure they're all fake. Name a scene and I'll confirm it. The famous monkey scene is fake. Real monkey, fake mallets. Then they had a fake monkey face, the "dead" monkey, spinning on a little device below the table. You can tell by most of them as they have multiple angles, and the creator appears in some of them.

I haven't see the later ones, but I hear they have more real footage. Like the chechen dude I hear is on it, that's real.
