As I posted awhile back, biographies are my favorites. I ran across "Then, Again" by Diane Keaton. I love her as an actress - but I have to say- I don't think I'd like her IRL. I can't put my finger on why but I wish I had not read this book now. (After I got about 1/2 in, I started just skipping around thru the last half) Just would not recommend it - especially if you like her as an actress.
Sidenote: Do you believe she thinks she is ugly and always has? I think she is one of the classiest, neatest looking women of her age there is around. And she is and always has been preoccupied with not being beautiful???
