I believe that B. getting the message across is the most important part of this film

In order:
B
E
C
D
A

B -- The movies were great for me who has read the books. For those who haven't, and especially for those who are of the Mouch mind out of ignorance, make the story and characters memorable and give evidence of Mouch vs. Rearden societal effects more plainly.

B - Getting the message of Atlas Shrugged right

Getting the message straight, which may be a little tough to do especially given Galt's long radio address, though it's spirit must be expressed, I don't think it could be duplicated in its entirety for the film: just my opinion.
Casting is not that important, it's the screenplay and the direction that will make or breakPart III.

One thing: Tell The Story. TTS That's all. The rest will take care of itself.

B. Getting the message of Atlas Shrugged right

Esai Morales's portrayal of Francisco was perfection in casting. He epitomized the free will and idealism of Ayn Rand's philosophy.

B) getting the message across. Determination, imagination and hard work to keep the profits of your ideas and creativity . Maybe make Rearden steel get into the automotive industry and other power sources. Example maybe they can make a new style car with the steel that is lighter and stronger and combine it with the new wave motor it showed in the beginning of part 2,make residential commercial power units with this technology so people can go off the grid(combine Rearden steels alloy and motor with wind and solar ?) Just thinking out loud >>>>>

To be fair with the book, the would have to be:

Dagny... Julianne Moore, Bridget Moynaham, Scarlett Johansson (well.. Scarlett doesn't fit the profile but I love her)
Rearden... Gerard Butler or Russell Crowe
Francisco... Robert Downey Jr. (and no one else)
Ragnar... Chris Hemsworth (awful actor, but fits the viking profile) or Guy Pierce

I know you can't get the original cast back but I really liked the people in the first movie over the second. So casting would be number one for me. The right director is crucial as well. Then, thirdly, for me would be the look of the movie. I just thought the first movie looked amazing for the budget and it really dropped off in the the second film. I hope you can get the people involved with sets and CGI from the first movie back for the third.

I think you have done great with getting the message of Atlas Shrugged across in both parts. I'm sure it will be the same for the third. I am really looking forward to the completion of the series.

The casting continuity can be remedied in an interesting way, in my mind. The Gulch could be used as a point of rejuvenation, Bringing Dagny from the worn out Mathis back to the confident Schilling. Francisco could also morph during the gulch sequence. Rearden will continue to age and become beaten (i.e. new actor) Until he joins the strike and could then revert back to Grant Bowler. Any other characters the writers/producers choose to revisit in the Gulch should also be cast as younger, more energetic versions of previous actors. All other characters (i.e. looters) should become more aged and beaten as they reap the effects of their ideals. The 3rd movie should uphold Rand's message of philosophy above all, but it should bring some type of continuity to the trilogy. i also feel that some of the technical aspects should be more accurately depicted. i was appalled at the treatment of The Taggart Tunnel sequence in part 2. Miss Rand did her best to understand railroads, industry, architecture, etc... before trying to depict them in her Novels. Anything less is a slap in her face.

Since I first read Atlas Shrugged when I was 15, I'll give you the actors that my family and I thought would be good for each role at that time.
Dagny = Diana Rigg
Francisco = Ricardo Montalban
Hank = Richard Burton
Eddie = Richard Jaekel
John Galt = Peter O'Toole

I took it as reflecting a company with some history, and longevity...like 20th Century Fox is still doing it, and doing it well enough to be a big player.

All the sadder when it finally fails through no fault of it's own....

B. Getting the message of Atlas Shrugged right!
It must be made clear to the low-information voters of America that altruism doesn't work and will eventually kill mankind's freedom, knowledge, prosperity, ambition, and self-worth. It must, however, be done on a level they can understand. This book shows and, hopefully, the movie will show that altruism is a blueprint for failure and total chaos. The movie should also demonstrate that the individual's freedom is what will ensure the group's survival. Casting is also very important. Try to get the original Dagny back.

Minor nitpick: did anyone else think "20th Century Motor Co." was an odd name for a company to have in 2014?

Do you know that Eddie's feelings for Dagny will be shown in part 3? They could leave that out without spoiling the story at all.

My problem isn't that Eddie is black, it's that he's the ONLY black in the cast. Makes him seem like a token. A couple of the disappearing businessmen, like Ken Danagger, could have been black. Better yet, a Denzel Washington type (obviously they weren't going to get the real thing) would have been perfect for Ellis Wyatt.

B. must be the top priority. I think this was maintained in Parts I and II. I would put A high on the must-haves list. While both movies captured the essence of most of the characters, I felt that neither one quite got D'Anconia's character right. Go back to the book; the answers are there. Please don't stray too far.

A. Bring back the main character players from I, or recruit Megan Kelly, or Laura Ingraham to play Dagny

What's up with you? Do you favor the laws of the old south where sexual relations between races was a felony? Anyway, Francisco in the movie isn't exactly how he's described in the book, either.... and he's isn't exactly a Hitler Youth in appearance - book or movie!

Ok, I know you said number on priority, but I think it is very important that A - Casting and B - Getting the message of Atlas Shrugged right are of paramount importance and in a lot of ways inter-related. However, I guess if I were to prioritize these in order of importance: B, A, E, C, and then D.

I think it's too little too late. This should have been done right from the beginning and it wasn't. The casting and acting have been sub par throughout and changing everything for the last movie isn't going to fix anything. What's the best solution? Start over. Cast people for the roles in the book not the role on the screen. The most obvious example being Eddie Willers. He is most certainly not black and casting a black actor to cater to the masses is the exact opposite of what should have been done. Again I say start over. Next time either get enough capital to make a great movie or find great actors to make the movie great. Both would be ideal but if you find great actors the money wont be an issue.

Get the message right. Do not delete entire storylines like AS2 deleted Jeff Allen's tale to Dagny about the Twentieth Century Motor Company. AS 1, 2, 3 would be better done as six films shot in the style of Lord of the Rings(all at once with the same characters).

Amen, Brother!

From my own personal life 13 people I know have read the book after watching the first and/or second movies. Of those every one is now more small government than they were before reading it.

As far as making a social change the movies are doing some good. I hope that they build a profitable franchise of products and services around and from the movies and long standing interest in the book. It would go far to educate and enlighten people about the evils of big government no matter what forms it takes.
