This has to be one of the most humiliating scenes in male nudity history for an actor. Viggo has to fight the bad guys totally naked in a turkish bath, so while he’s getting punched and thrown we see his average / small dick and balls from every possible angle. “It was slippery, painful, embarrassing” Mortensen said. My fav moment is when he has his butt turned to the camera, his butthole wide open (they blurred it in post I think!) and his balls jiggling.

Post-production actually blurred his anus hole but in this enhanced version you can actually see his closed tight butthole:
