The Catcher In The Rye as a play or film?  Not if J.D. Salinger has anything to say about it:

I keep saying this and nobody seems to agree, but The Catcher in the Rye is a very novelistic novel.  There are readymade “scenes”—only a fool would deny that—but, for me, the weight of the book is in the narrator’s voice, the non-stop peculiarities of it, his personal, extremely discriminating attitude to his reader-listener, his asides about gasoline rainbows in street puddles, his philosophy or way of looking at cowhide suitcases and empty toothpaste cartons—in a word, his thoughts.  He can’t legitimately be separated from his own first-person technique.

The letter from which the above is culled is currently on sale for $54,000.  You can see a copy of it here.
