The above poster art is for a selection of hard to find Mexican made horror films from the 1960's to the 1930's! I have yet to see any of them but I have put them on 'Hunt Down' list because they look extremely interesting. I was clued-in to the these movies by a friend linking to this BLOG POST that does a good job of making them seem quite enticing.
OK. I'll be honest.
I've already found three of these features in the darker areas of the web. And they have subtitles. The fourth one is still escaping me but, with a little luck, I'll track subs down for it as well!
