Interesting, I'd check it out on Netflix at some point but not in the theater.
I read Atlas Shrugged a few years back and overall enjoyed it, both for the expression of a philosophy through a fictional parable and the frequently bizarre subtext (what I saw as pretty clear-cut author self-insertion as Dagny + multiple quasi-rape scenes were an odd pairing to say the least).
I've never understood how so many people sincerely believe the principles of a work of fiction would translate perfectly to the real world, but I'd recommend the book to any serious reader. No idea how the movie will manage to boil down such a monstrous text to a few hours, but I'm intrigued to find out.
