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!
In this movie, we see Jamie Foxx's butt.
We see it at two occasions: Once in the locker room, as Jamie Foxx is wearing a jock strap and then in a bathroom as he is facing a urinal completely naked.
