According to Hollywood Insider, screenwriter Shane Salerno (Armageddon and Shaft)(... wait, what?!?) spent the past five years secretly filming a documentary about the author. It started as a five month project but turned into an obsession featuring 150 interviews ranging from those close to Salinger to people influenced by his writings. It isn't known if Salerno was able to interview the reclusive author directly, but there is word that several never-before-seen photographs and footage will be featured.
Even more astounding then the documentary being released is the fact that it has remained such a well kept secret for so long. Rumors are that anyone connected with the project had to sign non-disclosure agreements and post production facilities were only able to handle 20% of the footage at a time. Needless to say, that is some impressive lockdown for any film, much less a biographically based documentary.
Salerno is aiming for a premier at Cannes in May so that should give you just enough time to re-read Salinger's classic novel Catcher in the Rye to brush up on your literary lingo. I for one have dug up my old, dusty copy from underneath my uneven table to do just that.
