"Tarzan X - Shame of Jane" is a film that defies easy categorization. On the surface, it appears to be a straightforward adult film, but as the story progresses, it becomes clear that the filmmakers are attempting to subvert traditional notions of the Tarzan mythos.
Rocco Siffredi (as John / Apeman) and Rosa Caracciolo (as Jane)
Alternatively, could it be a combination with another movie? "Shame" (2011) by Steve McQueen? If the user is thinking of a fan edit combining Tarzan and Shame, that might be the case. But there's no official collaboration between them.
