mmm - what you're talking about then is probably this:
"Due to its graphic content, there are several different versions of
Cannibal Holocaust in circulation which are edited to certain degrees. Many uncut releases also differ in content as there are multiple versions of the "Last Road to Hell" segment of the film, which includes footage of genuine political executions from Nigeria
[8] and South East Asia. An extended version of "The Last Road to Hell" includes approximately ten seconds of footage not seen in an alternate, shorter version. This additional footage includes a wide-angle shot of firing-squad executions, a close-up of a dead victim, and extended footage of bodies being carried into the back of a truck. The longer version also includes different titles that correctly name the film team as they appear in the final film, while the shorter version gives the names of the film team that originally appear in the script."
