Thirties Horror Movies

I'm working on a short e-book on the subject of horror movies 1930-1939. I'd love to hear any suggestions that you may have on the subject of thirties horror movies! Is there a movie that you recommend? I've got a pretty good sense of what I'm going to cover, but if there is any true golden age horror buffs out there. Like I said, the only real criteria is that I'm only writing about thirties horror movies. I'm open to non-English movies, as long as I have some way of viewing them or accessing them with a minimum of hoops. In fact, there are three German movies for sure in the book already. Leave me a message on the form below, or a comment, or e-mail me at matt@cthulhudice.com if you have anything at all that you'd like me to cover, or that you'd like to add. P.S. The illustrator of the ebook sent me a very rough sketch of the first illustration, I thought I'd share. He probably wouldn't like that, but oh well.
