The main character laughs at the idea of using the multiple personality disorder motive or the serial killer motive in a screenplay because it is overused. Well, the movie itself uses the motive of a writer having a hard time producing his work and in the end writing about his struggles instead. Isn't this idea also a bit overused?
Also bring back Nick Cage.
I still cannot tell if Kaufman's oeuvre's common thread of loneliness is an outgrowth of something deeply personal to him or someone else; after all, every interview proves again his charisma and warmth and amity. I suppose that Donald, propped next to his inward brother in a wet swamp, captured the pic best: "It was mine, that love. I owned it. Even Sarah didn't have the right to take it away. I can love whoever I want."
La Roche at first loved his greens, then a woman, then whatever it took to harness that woman's love, even if it means robbing life of another, something he before so protected of his orchids. Not everyone can be a Donald -- and thank God for that (bad jokes are "good" because of their very paucity). But I think that he had the optimal approach to life: do not listen selectively but rather exhaustively, and do selectively choose which of these listenings actually affect your being, and which to tell, Fuck off.
