This one's a little less well known, but I fell in lust with this wonderfully awful movie called Fatal Exposure when I reviewed it a while back. The main reason I enjoyed it was because of our main villain and my selection as #14 on this list, Jack T. Rippington.
Jack, as he breaks the fourth wall (ala Mister Roper), lets us know that he is related to THE Jack the Ripper. I'm assuming Rippington's using a fake name, because that would take some balls to decide to be known as the Rippingtons. Not like relatives of Jason Voorhees decide to have their last name be the Machetes.
The movie itself is basically a series of gruesome murders with a half assed story about Jack drinking blood to be more sexually potent and have a son to pass the family tradition of killing to. As many people as this guy kills, I'm surprised he doesn't have a raging boner throughout the movie.
Anyway, you can tell the actor playing Jack is having a grand ol' time, because he is easily the best thing about this film. There's such a gleeful almost childlike joy in what he does you almost want to root for him instead of the moronic girlfriend who inadvertently helps him get models to kill off. She's so dumb she doesn't get the hint until the car radio practically yells at her who the killer is.
The gore in this movie ranges from Blood Feast like to pretty damn effective. The scene I've posted is an example of some of the better gore effects. So here's to Jack T. Rippington...making great grandpappy proud!
If you want to see the whole film, it's on youtube. I recommend you check it out.
