I'm reading the book right now, and got inspirations to cast the movie, since Hollywood's been thinking about adapting it for years.
Just when I finished it, I heard they already casted people for the movie.
Anyway, ideal Cast would have been:
Angelina Jolie as Dagny Taggart
Russell Crowe as Henry Rearden
Mickey Rourke as Ragnar Danneskjöld
Antonio Banderas as Francisco d'Anconia
and probably Brad Pitt as John Galt
I used gimp 2.6.8 to make this, it took me 1 rushed-hour (so that's why it's pretty sloppy), and i prefer to think of this as a conceptual piece rather than a finished work.
