The key source for this episode was the book Peg Entwistle and the Hollywood Sign Suicide by James Zeruk Jr., an excellently written and well-researched fleshing out of Entwistle’s life story in contrast to and in conversation with her legend. Some recommended sources include The Story of Hollywood: An Illustrated History by Gregory P. Williams; The Parade’s Gone by Kevin Brownlow; Lois Weber in Early Hollywood by Shelley Stamp; Material Dreams: Southern California through the 1920s by Kevin Starr; and Go West Young Women: The Rise of Early Hollywood by Hilary Hallet. Here is a music video for Dory Previn’s song inspired by Peg, “Mary C. Brown and the Hollywood Sign,” which features an actress (who looks nothing like Peg) acting out Peg’s approach to the sign.
