Before it's time...
This movie was so before it's time. Nobody remembers it, which is a tragedy. Since the whole idea of the villian who can't be killed, was developed in this movie.... before Jason, or Michael Myers, or The Terminator, and countless others of the genre.
I think this was one of Chuck's best movies actually. I always thought they would make a sequel, but alas, to no avail.
A real shame. Great grade B action/horror.
