In this movie, Colin Farrell appears fully naked and Matthew Davis only shows us his butt. But he has incredible abs, so we forgive him! In that scene, they are having sex with girls im the same bedroom. No foursome, just sharing the same bedroom. Colin's penis view is very brief as he walks in front of the camera.
31 minutes in the movie, Clifton Collins Jr drops his pants in front of his unit. He as a long shirt, so we can't see much. Only his dick head, cut, appears below the shirt.
This movie tells the story of Alexander the Great. The only nude scene is when Alexander is about to make love to his boyfriend Hephaestion, played by Jared Leto. Although the room is dark during that scene, we can see with some details the big penis and balls of Colin Farrell. Too bad we don't get to see them making love together!
