Actually, I don't think "What Ever Happened To Orson Welles?" was ever scheduled for publication before the spring of this year. Mr. McBride told me himself last year that the book would be coming out sometime in 2006. The Tiburon Film Festival, which Mr. McBride is moderating parts of, kicks off tomorrow, and I noticed the on-line program offers a plug for the Welles book stating it will be "available in 2006".
As an aside, I've often wondered why Amazon uses those odd release dates ("Jan. 1st, 1975") when an actual date hasn't been announced. Does "TBD" just not cut it?
