25 minutes in the movie, Reid Ewing is naked in a living room. He has a great body. We briefly see his pubes and then his butt when he leaves the room.
33 and 34 minutes in the movie, we see Reid Ewing's butt again as he is naked in the back yard. He is hiding is penis with a cushion, but he is not doing a very good job and we can briefly see his dick.

In this movie, Jesse Bradford was only 15 year old and it was the first and only time so far that he showed skin. We can see his butt briefly, as he gets arrested by the FBI. Previously to that he was showering but the camera was only filming the torso up. But it's a good 1 second of his beefy butt that can be admired. Other than that, I think this movie is great. Angelina Jolie and Jonny Lee Miller are the main stars and lead this movie very nicely.
