Okay, Lide z metra (1974) is unattainable, as far as I can tell. Has it been released on video or DVD?

Valerie a týden divu (1970) sounds quite chilling -- an adult Alice In Wonderland. This should be fairly easy to find on Ebay or Amazon.

Rock N' Roll Frankenstein sounds like something Harry Knowles might recommend. I'm totally into those kinds of b-trash movies. Very cool. This should be easy enough to locate. Brian O'Hara, the director, also produced that porn documentary Prince of Porn, about adult film director Phil Prince aka Joseph Scarpelli. Prince directed the notorious Taming of Rebecca, along with a few other roughies from the 70's.
