Content:  floor-pacing agonies of Once in a Lifetime’s gestation, the torturous rounds of re-writes and previews, sugarcoating everything about the romance of the theater that All About Eve had salted and pickled... Hamilton isn’t that bad, but playing an underdog of raging literal and metaphorical appetite, he purrs as a screen presence, his matinee-idol profile belying his character’s self-doubt. Nothing needy thumps around inside him. (Had Act One been made a decade later, Richard Dreyfuss would have been perfect.) What makes this Act One work are the crafty scene-stealers cast against Hamilton’s ingenuous Hart: Eli Wallach... Jack Klugman... and, most

Content:  all, Jason Robards as George S. Kaufman. With high-top hair, skeptical eyebrows that lift like Groucho Marx’s, and a resigned posture suggesting a body that’s a dried rind, Robards’s Kaufman is an Al Hirschfeld caricature come to life. Wallach, Klugman, and Robards—each had a distinctive grain to his voice, a variable velocity in his delivery. The contrast between these shrewd operators and the freshman crew playing Hart’s smart-aleck pals—among them future star George Segal as Hart’s personal prophet of doom—gives the movie its rustling texture as a Hollywood artifact, nearly everybody in it destined for greater glories on-screen. ,,"

Content:  Film rights were bought by Warner Bros, who assigned George Axelrod to write the script. Eventually the project went to Dore Schary, who had known Hart for a number of years. "I've tried to deal with Moss as I knew him," said Schary. "The film is more about character than the theatrical world. But I think his story represents more than just a guy trying to success in a tough, creative field, It's about his frustrations in trying to reach a dream, and then it isn't what he expected when he gets there. You might call it a typical American theme." Dore Schary himself was the basis for the character "David Starr" (played by Sam Groom). Anthony Perkins and Dean Jones were early contenders for role of Moss Hart. George Hamilton was socially friendly with the family of Moss Hart, and Hart reportedly wanted Hamilton for the role.
