I just watched the interview on the Anchor Bay's Four of the Apocalypse disc. Tomas Milian is always so funny on these interviews. But what really astounded me (as I haven't watch the film for a long time) is how sinister looking Milian is as a Chaco. He must be the ultimate spaghetti western villain. Psychotic, sadistic, immoral, drug-addict and just so fuckin' scary. But somehow there's also something very charismatic about him.
by the way, I just remembered that I have the soundtrack of this film. I had already forgot that I own it because I never listen to it. well, I'm listening it now...cheesy stuff!
