I'm still not sure if either of these is correct, I own Trog, and I somehow suspected that was it,
but I havent seen the whole thing to make sure (if I can find it that is!)
When I said I saw it in black and white, it was on a black and white tv, so it may have been sa color movie I'm not sure. Other caveman appearances: Encino man, Ice man, Altered states, The Quest For Fire...
But again, I'm not sure. By the way Bela didnt look like an apeman in that movie he looked more
like the rat faced man in the Stuart Gordon Masters of Horror episode. I'd appreciate other guesses
