What's really great are the completely hilarious movies.
With each one you get to play a game called 'who the hell is this actor playing?' because the cast changes each time, and they don't look alike. Hank Reardon in Part 1 is a blonde model. In Part 2 he's a gravelly voiced average guy. Welsey Mouch goes from a stout older guy with fantastic hair to a bald 40-year-old.
The shit's hilarious!
And don't get me started on the character dynamics. Okay, you got me started!
When Reardon is done humping his wife as she just lays there you can rightly think she's the problem....until he has sex with Dagny, where it seems like this ideal woman could be any other hole in the wall for the steel man.
And then there are scenes where they completely botch basic storytelling. Reardon sees Dagny on a job site and says, "you look like you fit right in here" as she wears heels and a suit in the middle of nowhere while walking on railroad ties.
They don't even get the monologues rights. Reardon's one before the tribunal is well done, but at James Taggart's wedding, Francisco (who was like 6' 5" in Part 1 and is Esai Morales in Part 2) gives his money speech. In the book it was interesting as he was having a polite discussion with other guests, and solidifies him as an intelligent hero. In the movie, he interrupts the groom's very brief remarks, making him a giant fucking asshole.
Point is: Watch the movies! They're amazing.
