The film is...Kong: Skull Island!
When reviewing Kong: Skull Island for the site, Bloody Disgusting writer John Squires noted that a particular scene from the film involving a huge spider and a soldier reminded him of the infamous impaling from CH. Was it intentional?! He tweeted:
I never expected a PG-13 King Kong movie to have a graphic & brutal homage to Cannibal Holocaust but, well, here we are. #kongskullisland— John Squires (@FreddyInSpace) March 11, 2017
And he was actually right:
Oh, and @VogtRoberts has been good enough to confirm that the Cannibal Holocaust ref was indeed intentional. Ha!— Mark Kermode (@KermodeMovie) March 12, 2017
The original tweet from Bloody Disgusting is under another cut as it contains an image from the scene in CH.
