Definitive proof!
5 November 2007 | by (Redondo Beach, CA) – See all my reviews

There can no longer be any controversy. This film gives definitive proof that such things as Sunn Classic pictures actually existed in the '70's, and they were very cheaply made. They actually did employ inexperienced actors to reenact eyewitness testimony of Bigfoot, Yeti, and Nessie close encounters. They actually did use old Super 8 film with inconsistent sound levels. They actually did have the chutzpah to have some tall guy wander around in a cheap Halloween gorilla suit. They actually did advance the testimony of people like a few frightened boy scouts who were telling campfire ghost stories as irrefutable accounts.

Peter Graves's ultra-serious "Dragnet" type of stoic narration is priceless; his mission to keep a straight face and tone in light of this amateurish production was more difficult than any he had on the Mission: Impossible series. The "scientific experts" he interviews look like they got their academic degrees from a box of Cracker Jack.

Check your belief/skepticism at the door; opinions on the existence of the creatures have nothing at all to do with experiencing this film. This one is just for fun, to laugh at the shoddy production techniques. The film takes itself way too seriously, with various lines of "testimony" that are fun to imitate, and sequences, such as the guy "psychromitizing" a box to discover its contents (um, why not just open it?), which make you laugh so hard you miss half of it. It gets a grade 7 on its laugh value alone.
