Yeah, it's finally being worked on now, apparently.
I think it actually should be turned into a comic by Buckley.
There is a speech lasting 56 pages told by John Galt, and it has moar words than any other english novel.
Here's a comparison of Atlas Shrugged to a typical CAD comic:
Atlus Shrugged: over 600,000 words
CAD: over 1,000,000 words.
