That's the one I was going to nominate.There are plenty of books that have been optioned for years: "The Demolished Man,"
I actually own an old paperback edition that says "SOON TO BE A MAJOR MOTION PICTURE!" on the cover.
That was back in the eighties . . . .
Would that make a good film, though?
It's been years since I read The Demolished Man, but IIRC, it was a very 'literary' book. That is to say--a lot of its impact depended on the fact that it took the form of writing.
I'm not sure how well it would translate to the big screen.
