I went to see Atlas Shrugged on the Friday it came out and the Saturday after! The movie itself was absolutely amazing, completely faithful to the book and produced exceptionally well for being an independent film.
The casting was done very well, all of the characters in the movie matched up with how I pictured them from reading the book. The acting was great, and the John Galt line making its first run was an amazing scene paralleling the accomplishment of getting Atlas Shrugged on the big screen!
Definitely go see the movie if you haven't already!
