The Greatest Cannibal Film Never Made?

.

Found this DVD cover while digging around for The Blood Sprayer's Italian Horror Week of an unidentified film entitled "Cannibal" at some all-Chinese hole in the wall e-tailer. It appears to be Cannibal Ferox, Cannibal Holocaust, Apocalypto, The Descent, The Screaming Dead, and some Naomi Watts flick with Apocalypto's tagline mixed together. Or most likely some very misleading use of stills!
