Angelina Jolie as Dagny Taggart? Brad Pitt as John Galt? There have to be better options. But, I don't personally think Atlas Shrugged should be made yet. The culture's not ready for it. Maybe in a few years, when the Ayn Rand Institute, Founders College, the VanDamme Academy, and other (explicit or implicit) Objectivist efforts have more effect.

It looks like it probably won't happen, in any event.
