From the point of view of a playwright, I find it very hard to have sympathy with screenwriters about anything. From the point of view of a playwright, they are ridiculously over-paid as it is. It is totally ridiculous that I've made more money on screenplays that never were produced than on plays that got produced and won awards. Or that you can make more selling the film rights to a play than on the royalties for the play. Totally ridiculous. But that's the marketplace for you.
