Val Guest? I still remember this one as a child. It left a mark.
Great movie. I've got it on a high quality Blu-ray disc, only now it's called Quatermass II, the second in a series of imaginative pictures based on the BBC's Professor Quatermass. My personal favorite is Quatermass And The Pit. (Also called Five Million Years To Earth.) It was filmed back in 1967 and I got to see it in a movie theatre up in Seattle. Fun times.
