I just saw this movie at the Brattle in Cambridge. It's been newly remastered, it's macabre and surrealistic and shocking and strange and kind of funny all at the same time. I only saw El Topo, I don't think I could handle staying up till 3 in the morning watching Holy Mountain right now, I'll probably watch that when it comes to the Coolidge. I highyl recommend El Topo, and from what I've seen of Holy Mountain that looks good as well.
See if it's playing near you!
