I picked this up at work because it looked interesting. It was actually better than I thought it would be due to the author's skeptical attitude about a lot of things, including whether or not Ernest Hemingway was God. Hemingway seems to have rubbed the author the wrong way by being a know it all. He also had some good stories about the Blitz where he was helping John Ford assemble wartime "propaganda" film footage [although that word was frowned upon by the director].
As a director, Parrish was not as high profile as Orson Welles or Howard Hawks. However, he did work with a lot of interesting people like Jean Seberg, Jack Lemmon, and Robert Mitchum; as well as on later films he did not care much for like The Bobo and Casino Royale. According to Parrish, Peter Sellers really was a jerk.
What strikes me is now much more literate old-school Hollywood people sounded. Although it was always about money, people did make some effort to put out intelligent films. I have a feeling his first book entitled Growing Up In Hollywood might be better because it talks about his work as a child actor on the Our Gang comedies as well as with Charlie Chaplin in City Lights.
