Luther the Geek(1990)

Luther the Geek is a fun indie film that's out on dvd from Troma. The film was made in 1990 and stars Edward Terry as an escaped mental patient whose teeth were knocked out at a circus as a child when he saw a freak in a cage clucking and biting chicken's heads off.

While in the mental hospital he made a set of dentures out of metal and sharpened them into fangs like Jaws in the James Bond films.

Anyone he kidnaps and terrorizes a family out in the country and kills people by biting them in the necks.

It's actually a pretty cool film.
