I'm reading bits and pieces of the book right now - it's really entertaining, but like all autobios, should be taken w/grain of salt, especially since Fuller could never be mistaken for a man interested only in cold, scientific facts. That is to say, to say the least, he liked to spin yarns and spin them quite colorfully. And according to a blurb by J Hoberman in FILM COMMENT, there's more than a few factual errors that slipped by the editors. Nothing too hazardous, but it gives you an idea of the book's overall sensibility.
Like Welles, I think Fuller is the kind of guy who requires a number of books from a number of perspectives...and the fewer that sell the "same old story" the better. I think there may be some potential for this, as (thanks to the new book, the Criterion DVDs, the new Fantoma DVD of STREET OF NO RETURN, and the frequency of his movies getting airtime on TCM) he may finally be getting some recognition beyond the realm of the hardcore cinephile.
Andrew Laskos makes a few pointed observations on Mobius
That said, Fuller's great, and among his masterpieces, PARK ROW is as good as anything Welles ever did! PICKUP ON SOUTH STREET and WHITE DOG are also great.
