THEM! - 1950's
Giant Ants caused by radioactivity! Very scary - THEN!
I saw that movie! (of course not in the 50's) It was later played somewhere in the 60's and scared the bejebers out of me. (was a wee tot when I watched it in black and white) I can still remember seeing the fleshless face of the cop when his body was thrown on the desk.
But I have to agree with LeahAnn that RHPS is the BEST!! (although not considered sci-fi)
Lets do the time warp again!!!! Come up to the lab... and see, whats on the slab!!....... I see you shudder with ........AN..TICI........PATION!!
Great, gonna have all those songs stuck in my head all day...
