This was one of the first "horror" films that I watched as a kid and I remember that I slept with the light on for weeks, it was not like the recent horror films filled with gore and splatter, but its the indication of the terror that makes it scary. I recall that there was a chase scene where the demon is chasing Dana Andrews in a car, and i remember that he plays some one who ridicules the occult which makes the satanic leader mark him to be killed by a demon, I would hope that they do not remake this films has with all remakes you can't beat the original. The only same film that has that foreboding feeling to it would be something like the Blair witch Project, which has that creepy feeling akin to when I first saw the Omen. It does'NY have lost of blood or gore in it but the film is still one of my all time fav horror/suspense films.
