Two movies that I remember as being really, really scary were a couple of Roger Corman ?B? movies that were shown as a double bill (remember those?) in 1957. I was 10 years old and my brother 9. We went to see ?Attack of the Crab Monsters? and ?Not of This Earth? (not to confused with the cheesy remake starring Tracy Lords). After watching them, neither my brother nor I could sleep that night?we stayed up all night with our light on. I realized many years later that what was so scary about those movies was that they got inside your head. I believe that is what makes a horror movie work. That?s why black and white movies were so good. They made you rely on your imagination.
Today?s horror movies are mostly too commercial and rely on visuals to ?scare?.
Oh to recapture those old days of the ?B? horrors: Hammer Studios, American International, etc.
