Good: A college student (Dirk Benedick) is hired to be the assistant to a local ophiologist (the great Strother Martin). Bad: the doctor is crazier than Dr. Frankenstein and dreams of turning humans into snakes. Really bad: starting with his new assistant! Yikes!
At first, Dirk is happy with his job and even enamored with the doctor's nerdy daughter, but then the doctor starts giving him shots to help him build up an immunity to snake poison but in fact he's pumping poor Dirk up with some experimental bullshit that slowly turns him into a snake! The slow behavioral transformation and eventual physical transformation was fun to watch, but I had a hard time believing that Dirk's character was so stupid to not notice what was happening. But hey everybody can't be a smrt as me.
The story sounds kinda sssssssucky and it kinda is, but Strother Martin's performance is truly disturbing and he easily carries the film into Worth Watching territory. I do wish the movie had been just a little more risque though. Example: the leaves covering up the skinny dipper's nudity. This is a horror movie, if you're too goddamn chicken to show a naked butt cheek then the audience knows there's not going to be any violence worth a damn on the horizon. Oh well, that's my main gripe. Overall the movie was better than I expected and I'd watch it again, but just remember this is an early 70's studio-backed horror movie, so don't expect anything outrageous.
