I actually thought this was from the '50s or '60s
It never occurred to me when I saw some clips of it on You Tube, until I spotted a comment saying it was 2001. I like to check out these spoofs, and I've found many on that site. Now we know why the monster looks so utterly fake: obviously it's low-budget, but on top of that, it's a spoof of low-budget movies.
