It Took Guts (1979)

Directed by Eric Forsberg

A teenage boy, troubled and alone wanders the grassy hills looking for something. He settles on a slope and searches for some activity to amuse him. He begins to pick pieces of his body off and taste them. This seems like a good thing to do. So he removes his eye, his face and finally his own guts and eats them all in an orgy of ecstasy and gore.
