Last Cannibal World (1977) aka Jungle Holocaust
The Mountain of the Cannibal God (1979) aka Slave of the Cannibal God
Eaten Alive! (1980)
Zombie Holocaust (1980) aka Dr. Butcher M.D.
Of the four I've only seen Zombie Holocaust, the other three are ones I'm aware of but haven't gotten around to checking out yet.
