a welles bio by clinton heylin coming out feb 2005 won't diminish the image.
march last year clinton spent a week at my home looking over my welles collection, and we compared notes on our research. when i would get into a reverberation about welles being difficult, loony, gobbling diet pills, etc, etc. clinton didn't want to hear any of that. clinton is a great guy, we had a great time the week we spent BSing about welles and watching welles tapes, and it was clear to me that he has the proper reverence for his subject, the type of reverence that does not diminish the image.
my personal taste, i would put that stuff in a book, but i look at it a bit different than a thomson, or higham would look at it. i look at those things with amazed amusement rather than using it to beat the subject with. the outrageous stuff houseman reported in his book, i loved. made welles an incredibly interesting, colorful creature, and made the book a blast to read.
