Two comments: first, Joe Mantagna isn't a real Supreme Court justice - he just plays one on TV.
Second, there was a movie made about 10 years ago or so called "The Temp". It was filmed here in Portland and there was a basketball game in it. They filmed the game at a middle school where one of my brothers-in-law taught and they asked him to play a referee in the scene.
If you ever see the movie, the really tall guy playing a referee is my brother-in-law Jim, and his mechanics are perfect.
I wonder how that happened?
