Mid movie, Jesse Spencer, the famous doctor or House M.D., goes running naked to the ocean. We first see his butt, slightly out of focus. No full frontal at that time, although when he is running, we almost get to see his dick. At the beginning of the second part, we see him swimming again, and we see clearly his butt, and then again when he gets back to the beach. Towards the end of the second part, Jesse is naked again on the beach. But a frontal is avoided by the camera and we only get to see his butt.
