I hope you're wrong too. There are already rumblings in Hollywood that nobody will touch Baldwin. Not as a actor, writer or producer. They don't want his stigma attached to anything they may be doing. Besides, he's already known as being a bit of a prima donna and a PITA to work with.
I also predict that if he manages to finish Rust, it'll fall flat on its face and lose money. I might watch it once it gets to TV just out of morbid curiosity, but there ain't no way in Hell I'd pay to see it. Many others feel the same way.
