"Hemingway, who is parodied in the film with dialogue like “no subject is terrible if the story is true and if the prose is clean and honest,” was envious of the seemingly effortless lyricism of Fitzgerald’s writing in works like “The Great Gatsby.” In “Midnight in Paris,” Hemingway tells Fitzgerald that Zelda, a writer herself, sees her husband as a competitor. But “A Moveable Feast” offers a more full-throated account. Hemingway grew to despise Zelda, partly because she had betrayed Fitzgerald with a French aviator and partly because he blamed her decadent tempestuousness for ruining her husband’s productivity."
