There is no more deep, dark, and mysterious place than the anus. The brown eye shot is one of the rarest in cinema for a reason--to reveal that hidden spot, the lighting must be bright and direct, and the ass cheeks must be spread.

However, thanks to the wonder of Blu-Ray, even a shadowy hollow can now be defined as 100% brown eye action. Case in point, the asstastic Jenny Agutter in Walkabout (1971). What we previously though was just crack can now be revealed as the rear port!

This one's definitely going in our "Did I Just See a Butthole?" playlist.
