I was searching for this for years. I saw this trailer back in 1982, and having just watched Texas Chainsaw Massacre and being scared witless by it, expected more of the same from the director, which, based on the teaser, looked to be what was in store. The week it came out however, a friend thought it would be fun to take a pile of magic mushrooms and see it tripping. I still remember walking into the cinema out of my skull, getting a flashback to this teaser and expecting another The Exorcist, and almost walking out before the film began. Of course Poltergeist isn't particularly horrifying or scary, outside a couple of scenes, but I never forgot this trailer. I wish they'd scored it a little more like this too, as I found the Jerry Goldsmith music a little too bombastic for the visuals.
