The Cannibal sub genre wasn't that popular with the BBFC.
Though alot are getting released now with just the animal kills cut, the last submission's of Holocaust, Ferox, Eaten Alive and Mountain of Cannibal god were cut for human violence as well.
I think Bruno Mattei's Cannibal film, not sure of title, but its like a prequel to Holocaust, was rejected about 2000. I think it may have been Mattei's last film, not sure .
The Cockfighter's another that I think still presents problems., as does Devil Hunter, (Angel, Vince.?) the film, not our member Devil Hunter.
I recon each time they get a new Jess Franco film in for classification, it has them running for the sissors....LOL
