IFC has been showing 50's sci-fi/horror B movies on the weekend for Halloween. I love these.

Check out the scene at 1715. The sheriff knows how to take a man down. There is another crotch shot later, but this is the really funny one. He just walks through the door and bang, bang, bang! Nobody questions it, although he couldn't have known what was going on.
