Well, DR JMK - basic similarities in the two books, of course, but ATLAS SHRUGGED is the more complete objectivist manifesto.
Al Ruddy had the TV rights for an ATLAS SHRUGGED mini series that was also announded for TNT a couple of years ago....that also has now gone by the wayside.
ATLAS SHRUGGED is my favorite book EVER, and I think the characters (though mostly one dimensional) are fascinating. And the description of the book is still one of my favorite blurbs.
