But it looks like I pfffffted too soon. Comingsoon.net talked to Perelman this week, and he told them that he's finishing up the script, and that Lionsgate wants to start shooting in December. So, uh: it looks like this might actually happen.
I would commit atrocities to get my hands on a copy of Perelman's screenplay. I can only imagine what it does to condense the thousand-page-plus book into even a very long movie. What worries me most is that the novel doesn't really exist without Rand's politics, if that makes any sense: they're so integral to the story that cutting them out would make everything else pretty much pointless. And I'm not sure Hollywood -- even the relatively adventurous Lionsgate -- has the stomach for a politically faithful adaptation.
