Overlords of the U.F.O.
This documentary puts forth the theory that UFOs are actually beings from another dimension, and reviews past incidents of UFO sightings in support of that theory.
Cheap, cheap, cheap "documentary" about UFOs. There were dozens of these things in the 1970s and this one just might be the worst.
Not actually a Sunn Classics film, this paramormal doc starts out covering UFOs, but starts branching out in several odd directions, eventually settling on a public appearance by Uri Geller in which he only mentions a UFO photo he took in passing. Most stories are narrated by the host, illustrated with still photos. It’s lame, but at least it gets points for outrageousness, at one point blaming cattle mutilations on invisible brain monsters.
