The author of Catcher in the Rye, one of the most popular and influential books of the 20th century, made no public appearances and published no new writing for the last forty years of his life.  A new documentary reveals extensive new information about his life and, most intriguingly, the prospect that there are files of writing he did over the decades that may be published.  Deadline Hollywood has the first look at the trailer, featuring some of the other top literary figures of the era and writer Joyce Maynard, who lived with Salinger for a short while after he wrote a fan letter about her New York Times article that became the book Looking Back: Growing Up Old in the Sixties.
