Glen Charlock, Denis, and Adrian Prussia miscast
Sorry, there was just something about each that didn't rise to the level of perfect casting like everyone else in the movie, especially Glen.
"I'm in a *beep* Cameron Crowe movie!"
Heh, good one.
Otherwise, I thought Prussia was ideally cast. Deeenis is supposed to be a translucent soul drifter, barely there. I think it comes across in the acting.
