Jonny Lee Miller
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.
In this movie there is a lot of drug use but also sex scenes, including full frontal nudity from Ewan McGregor and one quick scene with Ewen Bremner.
