The author of The Catcher in the Rye and Franny and Zooey died in January 2010 after living for more than 50 years as a recluse in Cornish, N.H. Shortly after news of his death emerged, Hollywood screenwriter Shane Salerno announced he had been covertly working on Salinger, an independent documentary probing the author’s sheltered existence. Susan Lacy, American Masters executive producer, learned of Salerno’s film while attempting to procure the rights to an unrelated Salinger biography for the program. Salerno — whose screenplay credits include Alien vs. Predator: Requiem and Oliver Stone’s Savages — agreed to produce his film for American Masters after Lacy contacted him. Salerno is a fan of American Masters and says he taught himself the craft of documentary filmmaking by watching the biography series.
