I have seen this movie and it is very average.
It is let down not by some very poor acting.
A couple a curious scenes are depicted, Elvis is rescued by Stanley in New York 1976 ie, after leaving the stage Elvis is attacked by some nut with a knife.
In another scene Charlie Hodge is depicted as sexually assaulting a woman, with Stanely coming to the rescue again.
I don't think that charlie was like that to be honest, he was turly a great man. The stanleys are like there mother they can't seem to get there stories straight either.
