Hey Skel, thx for the UK quad poster pic. First time I've seen it. Kinda neat, spare design, if crudely executed.

It's an interesting contrast to what Dick Gordon remarked (in one of our Mr Weaver's interviews) about its US advertising -- that MGM wanted to play down the film's horrific side in favor of a "science fiction/science fact" angle. And sure enough, when I saw the film theatrically at the ripe old age of 7, what a completely unexpected & pleasantly terrifying revelation that monster was. Not sure if that was MGM's intent, but it worked.

Another note. On the rare occasion these days that I chance to meet anyone name of Charles, I internally regale him in the way the monstrous Bill Edwards finally confronted brother Marshall Thompson at the film's climax -- with that muffled, growly "CHUCK??"
