1. In biopic terms, the story and structure is understated and not unnecessarily contrived. Except that one scene.
2. Casting Steve Carell seems risky, especially considering when this film came out. But it turns out that he was perfect for this role. Funny, a stressful person to engage with, but never a character worth laughing at.
3. Casting everyone else turned out weirdly well. Channing Tatum and Mark Ruffalo play incredible brother-foils. Although, maybe the actors playing du Pont's associates…
Its practical effects really characterize its world. Misfortune lingers in every place and on every person. In some other movie the amount of pyrotechnics, work-related accidents, and sudden death might have been overkill, but in this context it was just some weird slice of life. When the credits started rolling I felt exhausted and that was nice.
