Can't wait for Volume 3 "One Man Band." Hopefully as expressed on the excellent new Wellesnet home page Mr. Callow will consult all the detail - forensically - about Welles's last, ultra-independent-minded years. I don't believe anyone else has done so in one place.
One thing certain other writers on Welles's life have done is to ignore the need to have a precise understanding of the actual facts before creating a synthesis or spinning a legend. One writer explicitly dismissed everything Welles did after 1965 as a long slide into the gutter, and refused to write about it (though supposedly writing A Story of His Life), declaring that Welles's last unfinished film must not be seen. Mr. Callow seems to be of rather more curious and rigorous mind.
In connection to the Macbeth film discussed on the home page here, I notice an error (?) Mr. Callow makes in both the hardcover and later softcover editions of Volume 2 "Hello Americans." Mr. Callow omits to mention Welles's Salt Lake City Macbeth in the Appendix on Welles's theatre work during the years covered by this volume (and discussed with unique éclat in the text). Surely this staging of Macbeth was a bona fide production, though occurring in Utah?
I'd advise Mr. Callow to drink long and deep and joyously of Wellesnet as part of his characteristically fine and omnivorous research. This is the least explored, least understood part of Welles's life. IMO Mr. Callow has a chance to produce a really original volume here. Power and strength to him!
