MY 2 CENTS, offered at no charge to the members of wellesnet:
totally agree with jeff's list. also carringer has a way of assigning credit to the studio janitor for all of the great things in kane, and ambersons.
the maurice bessy book is interesting. focus on ck, and focus on ow are both well worth the trouble of getting from library and pirating yourself a copy because both are out of print. the rutger's CHIMES AT MIDNIGHT is excellent. the james naremore book is super excellent. the frank brady book is the only bio really.
the bret wood OW is a tremendous resource.
the houseman book, A RUN THROUGH, is a tremendous read. it said some awfull things about welles that i felt were exagerated, but hillarious, and true. this is probably, to me anyway, the 4th most interesting welles book, after frank brady, this os ow, and the naremore book.
rutger's touch of evil is a helpful book, the lebo ck book is excellent. the john russel taylor book and the james howard books are pedestrian. the mcbride book is very good. the peter cowie book is suck-ola at best, it's not mean spirited, it's just lame.
and a lot of people think the OW, SHAKESPEARE, AND POPULAR CULTURE is a great read. i have not felt like that yet. it's in my library, but so far it's been another $15 pissed away on something else taking up space.
and PUT MONEY IN THY PURSE is excellent. only it's topic i think keeps this from being considered a classic piece of writing. macliammoir's writing style in this little offering is absolutely marvelous. have read it 2 1/2 times.
