I've got the EC Entertainment Ultrabit DVD of Cannibal Holocaust which, according to
DVD Compare is the longest version of the film.
According the film's IMDB and Wikipedia pages, the full runtime is 95 minutes, however the runtime of the EC DVD is 91 minutes. The EC edition is the only version of the film that I've ever seen, but when watching it it doesn't seem as if any scenes have been obviously cut or censored, and it contains all the acts of animal cruelty listed on the Wiki page in full (as far as I can tell).
So the question is, is there a 95 minute version out there?
