I have three editions of Cannibal Holocaust; Grindhouse 25th Anniversary Edition (ltd 11,111), the EC Ultrabit Edition (ltd 4000) and the EC Remastered version...
The Grindhouse release is awesome for the animal cruelty free version but looses a couple of seconds elsewhere which is where the Ultrabit comes in!
Looking forward to a blu ray that offers both an uncut print and the cruelty free option together, that said I am amazed how relatively unscathed this came through the BBFC!
