Well, here is some guy's review of that movie:

Oh, but you may want to try to find the Simitar VHS release from many years ago.
There's a recent DVD release you can find on Ebay; it's okay but I noticed it was a TV print, shortened by a minute or two. The Simitar VHS release is as far as I know complete.
Supposedly there is a widescreen DVD put out by some company but I have not been able to find this.
By the way, I think I may have seen "Sasquatch: The Legend of Bigfoot" on TV, way back in the late 70's! It might have been a similar film, but back then I watched all the Bigfoot movies whenever they showed 'em on TV. They were great.
