A new documentary on J.D. Salinger claims more Salinger books are coming:

But a forthcoming documentary and related book, both titled “Salinger,” include detailed assertions that Mr. Salinger instructed his estate to publish at least five additional books — some of them entirely new, some extending past work — in a sequence that he intended to begin as early as 2015.

The new books and stories were largely written before Mr. Salinger assigned his output to a trust in 2008, and would greatly expand the Salinger legacy.

One collection, to be called “The Family Glass,” would add five new stories to an assembly of previously published stories about the fictional Glass family, which figured in Mr. Salinger’s “Franny and Zooey” and elsewhere, according to the claims, which surfaced in interviews and previews of the documentary and book last week.

Another would include a retooled version of a publicly known but unpublished tale, “The Last and Best of the Peter Pans,” which is to be collected with new stories and existing work about the fictional Caulfields, including “Catcher in the Rye.” The new works are said to include a story-filled “manual” of the Vedanta religious philosophy, with which Mr. Salinger was deeply involved; a novel set during World War II and based on his first marriage; and a novella modeled on his own war experiences.

Here’s the trailer:
