You guys have helped me out twice in the past, and I'm back for my third request. Here is what I saw that scarred my brain forever.
I was probably 7 or 8 years old, so this would've been in the early 70s. And I believe I was at a drive-in with my parents. There was a coming attraction playing before the movie, and one image from that trailer burned into my mind. It was a toy robot – the old fashioned metal toy robots that every little boy owned decades ago. The toy robot was walking, when suddenly something injured it (my memory is fuzzy when it comes to what type of injury the robot sustained). Anyway, the robot fell over – dying – and from a gaping wound in its metal belly, GUTS STARTED TO SPILL OUT! Holy crap, we're talking bloody, red, gory GUTS! The robot had actual intestines!
Any ideas? Besides that one freaky image, the memory is very murky. But I'm about 98% sure that I didn't dream this. This film is out there somewhere.
