Interesting thesis. I wonder how you can incorporate Nina's experiences as an actress (Act. IV) into your thoughts. For all of the pain she has experienced, hers is probably the most 'alive', the most fulfilled. Whereas the writers, even when published and successful, still view the world from a safe distance and never truly experience. Which probably explains their attractions to actresses.
I wish I had more time to think on this right now...but I'm getting the frig outta work. If I can actually form a coherent opinion, I'll post again.
