Alternate versions

The Grindhouse Releasing re-release, as well as the 2005 DVD, features a scrolling warning before the film from the company stating that the film is uncut and uncensored and while they do not support the "artistic decisions" of the film, they do support free speech. It also plays part of Riz Ortolani's music score in the background.

The Japanesese Laser Disc is uncut at 95 minutes, but is optically censored.

The USA Grindhouse releases (the Limited Collector's Edition and the Deluxe Edition) are both uncut at 96 minutes. These versions include The Last Road to Hell sequence completely intact. The only other releases with the Last Road to Hell segment intact is the EC Entertainment Limited 2-disc Ultrabit edition and the Deluxe Collector's Edition from Siren Visual Entertainment.

The EC Entertainment Deluxe Collector's Edition (single disc) is uncut and runs at 94 minutes, but is missing five seconds of the Last Road to Hell sequence. The EC Entertainment 2-disc Ultrabit Limited Edition is also uncut and includes the complete Last Road to Hell sequence.

The 2-disc French Collector's Edition from Opening Distribution is uncut, but is also missing several seconds from The Last Road to Hell.

The 2-disc release from in Australia from Siren Visual Entertainment is uncut, including the full Last Road to Hell sequence. This release is an exact copy of the USA release from Grindhouse Releasing.

The Australian DVD, released by Siren Visual Entertainment in 2005, is the same version as the US Deluxe Collector's Edition 2-disc released by Grindhouse. The film is the complete and uncut 96 minute version, is coded Region 0, and is in PAL format. The DVD also contains the complete Last Road To Hell sequence.

German video release "Cannibal Holocaust" from the label Astro was uncut, but was banned in 2000. The old first release with the title "Nackt und zerfleischt" (Naked and Mangled) was heavily cut and is still available.

The film became one of the most notorious video nasties and was unavailable in the UK for many years. The 2001 version from VIPCO (VHS and DVD), rated 18, was heavily cut by 5 minutes 44 secs by the BBFC and removed all footage of genuine animal killings and mutilation, as well as editing the rape scenes and the infamous torture scene with the spiked mud-ball. The later release from Blackhorse featured the same cut print. In 2011 the uncut version was again submitted to the BBFC for DVD release (on the Shameless label) and surprisingly most of the previous cuts were waived, with only 15 secs of cuts required to the genuine killing of a muskrat.

The UK Blu-Ray disc from Shameless includes a number of differences:

• A United Artists Europa Inc. title is placed at the beginning before the film starts.
• The opening music is an alternate take that differs when compared to the mono version.
• The subtitles for the foreign scene has been changed; although they still have the same meaning.
• The killing of the muskrat has been replaced with various alternative shots.
• A very brief second has been added to the end of the muskrat scene to make the cut between this and the adulteress punishment scene smoother.
• Subtitles added to the scene where Miguel tries to make peace with the cannibals.
• The last road to hell has been fully restored although the music is slightly different, and the quality has been downgraded slightly.
• A few frames have been deleted at the beginning of the scene when Professor Monroe is interviewing Alan's father. This makes the cut more jagged.

The heavily censored version made its way to India certified with an 'ADULT' rating with a run time of 1 hr 15 mins, but was never censored by the CBFC (Cert No.: 1412).

This film was banned in Norway, until 2005 when it was finally released on DVD, completely uncut only with about 10 seconds missing from the "Last Road to Hell" sequence, presumably due to print damage.

The scene in Spanish, about seven minutes in, has various different versions. In some cuts, there are no subtitles. Most recent releases have subtitles, but the translation of the words varies.

The Professional Cine Media Laserdisc is also uncut at a running time at almost 92 min (PAL) from Holland.
