I was very young, approximately 1969. At the drive-in with my parents, it was a double feature ,and after Swiss Family Robinson ,there was this horror movie ,I only remember one image.
There was a clothed body with its head apparently chewed off with only a bloody neck stump exposed, then they pan over to the other side of the room and there was a guilty looking cat sitting there.. It might have been a black cat I don’t remember for sure. I’m pretty sure that the scene was alluding to the fact that the cat was the killer? I don’t know for sure.
Torture Garden, scene here: https://youtu.be/2QkECYGtwbA?t=36m26s It horrified me as a kid!
My God I think that’s it! Looks like it’s a classic film more than I ever knew. I can’t wait to watch the whole thing now. Thanks for linking me the scene. It was a little different than I remember in my vague memory but that’s gotta be it! And it’s the right year as well. The image of that cat when they zoom in on him as the guilty killer has stuck with me my entire life. Thanks so much!
Thanks Grover! Now get over to this other post (http://irememberthismovie.com/science-fiction-on-another-planet-2/) and help us sort that out.
