Only thing I've seen of Deodato's has been Ultimo mondo cannibale (1977), also known as Jungle Holocaust. I liked Sergio Martino's La montagna del dio cannibale (1978), or Mountain of the Cannibal God, more.
At least both of the above movies were better than the founder of the sub-genre, Il paese del sesso selvaggio (1972), or Man from Deep River. Talk about a movie that's hard to get through.
That said, this film is one I've known about for quite some time, so I'm happy to see that it appears a decent flick.
