I think what it comes down to it is old-fashioned insecurity. There is no doubt in my mind that Welles is a fantastic filmmaker, and even personality - but there does seem to be a problem with focus in his life. Also I wonder why Jaglom never funded or actually produce a Welles film? Yet he is with him complaining and bellyaching about this and that. In a funny way he comes off as Iago to Welles Othello.
Welles is also has harsh opinions on individuals which I think are totally unfair, and worst, makes him an over-sized cry baby. The book he did with Peter Bogdanovich is pretty great because one, it exposes Welles' strength as a filmmaker and figure, and two, it also showed his catty-side. This book, only shows his catty-side, and it is not a nice portrait of a man, who like Nixon, shouldn't have his conversations taped.
