Here are some I can think of right away. No particular order. 1. Alien 2. VideoDrome 3. Eraser Head 4. Phantasm (1st one) 5. Halloween (1st one) 6. The Thing From Outerspace (old and new) and, I can't think of the name, the one where the other world opens up from the cube...fish hooks grab the guy...??? Oops, there's the doorbell again.
