Interesting. I'll check it out and give a watch. Didn't think the film went that much into all that. That's right up my alley of interest.
Have you ever seen "Man On The Moon" with Jim Carrey? It's the life story of famous comedian (and REAL weird guy- Andy Kaufman who went from stand-up comedy to playing on TV series "Taxi" among other things).
It's a great flick- won't do a give-away, film wrecker in case someone hasn't see it and wants to. But in it he seeks "treatment" down in one of the, to say the least, wild "clinics" in Mexico. Very well done scene. That film is an old fave of mine- Jim Carrey to me, when he plays other people is brilliant, he literally became Kaufman and the film is funny as heck too boot.
Check it out too.
