Jeremy Irons's part of John Tuld was originally offered to Ben Kingsley, but due to other projects he couldn't play the role. Billy Crudup and Tim Robbins were also interested in taking parts, but had to refuse due to other obligations.

The CEO's name, John Tuld, rhymes with the name of the ex-CEO of the now-defunct investment bank Lehman Brothers, Richard S. Fuld. Lehman Brothers, like the firm in this film, found themselves catastrophically over-leveraged in mortgage-backed-securities in the financial crisis of 2008. They eventually declared bankruptcy, and Richard Fuld was heavily criticized for his involvement in these events.

Carla Gugino was attached for over a year to play 'Sarah Robertson' but had to withdraw last minute due to another project. Fortunately Demi Moore was able to join the project.

Steven Spielberg's name is misspelled in the "Special Thanks" section of the closing credits.

The use of rooftop helipads in NYC was banned after 9/11.

When driving home from the office, Sam is seen in his car wearing a different dress shirt than the one he wore in the office. After being called back, he is again wearing the shirt he wore during the day. Then, the next business day he is wearing the one he wore in the car the night before.

John Tuld: Maybe you could tell me what is going on. And please, speak as you might to a young child. Or a golden retriever. It wasn't brains that brought me here; I assure you that.

Seth Bregman: Will, did you really make two and a half million last year?

Eric Dale: I run risk management... it just doesn't seem like a natural place to start cutting.
