What was wrong with james arness in the b&w one?
Once 1979 Alien came out everyone wanted to have that level of sfx in their scifi horror movie. Gone was subtlety. Ut realize there were a lot stricter movie decency codes in 1951, and also far lower movie bugets in 1951, plus so much of the tech and materials to d this wasnt around in 1951.
I saw that when I was a boy. Scared me for a long time. Years later I couldn’t believe it was the good man of the law of Gunsmoke.
