Charles Affron’s biography of Lillian Gish
Just finished reading Mr. Affron’s bio Lillian Gish: Her Legend Her Life. It came out in 2001. Very informative about the early years as well as her later ones. I think she had a very happy life. She had a spine of steel despite her cream puff delicate appearance, but she was no Jekyll and Hyde. She was always polite but firm.
Ultimately, I think she was more important to the birth of a credible screen acting philosophy than anyone else.
