Wheeler Dixon and Sidney Paul made so many of these movies, and you may get confused because they all seem so similar. Yet you must go down this corridor and expose yourself to each of their films.

What connects these films? The fact that they continually remind us that aliens want to eat us. How do they know this? They’re so sure of it. They even say that alien civilizations might view Earth as “nothing but a slaughterhouse, an alien food breeding ground.” Paul calmly asks frightening queries, like “What will save us then?” and “Are we being watched by creatures from outer space?”

This movie is washed out; it has wild folk music mixed with library sound effects, and a rambling narration that seems to ask you questions every few moments, and I always find myself having a conversation with it. Yet this is the kind of thing that totally speaks to me, a nearly lost film that has never come out on DVD, even, one that’s hiding on YouTube and feels way stranger than any of the Ancient Aliens shows that litter cable.

There are a hundred or more ideas in here. If one of them were true, it would destroy your mind. Do aliens live inside the sun? Are ancient cave drawings and burial tombs in Greece and Peru blueprints for fuel thrust systems and a pressurization chamber? And, as always, when are extraterrestrials going to treat Earth as if it were Golden Corral?

It exists in a strange limbo, too psychedelic to be a serious documentary and too earnest to be pure fiction. Because this film relies heavily on public-domain NASA footage, military archives, and stock science clips, it feels like a dream of 20th-century progress reinterpreted through a lens of impending doom.

You can watch this on YouTube.
