Salinger is dead, so he can't be offended. If I were his kids, who put up with his crazy ass shit all his life, I'd milk this for all I could.

I think you're right about the odds of finding critical success by adapting any of Salinger's fiction to film. But you, of all people really, ought to know that any adaptation of Salinger to the Sliver Screen would probably see a sizable financial return, which is the only reason any movie studio ever does anything.

That said, as a Salinger fan, I AM FUCKING STOKED to get my hands on all of the unpublished stuff that the old bastard's been hiding in his attic for forty years, Terminator fan fiction and all.

I'm all in favor of his estate releasing his unpublished work, especially if it's true that it went unpublished primarily because he himself simply didn't want to deal with the bullshit that comes with publishing.

But if petitions ever did any good, I'd sign one in opposition to selling the film or television rights, in a heartbeat.

But you know his estate will yield to the temptation to make shitty movies off of his carcass, ala Philip K. Dick's daughters.
I can just see Catcher in 3D, with tie-ins with 7-11!
SLURP!!!
