FYI - This movie is considered public domain now and can be downloaded for free from a few websites.
I can't remember which sites off-hand, but search for the movie by name and you'l eventually find it, that's how I got it.

Most versions of ZONTAR are fuzzy and unfocused but
Retromedia did a remake that's much clearer.
You'll also find THE EYE CREATURES on archive.org
Choose the big download-- it's worth it.
