Feelin like some stock market porn?
I just re-watched a lesser known movie, Margin Call. Underrated IMHO. While not named, it is largely based on the internal events happening at Lehman Brothers during the GFC collapse.
I had re-watched The Big Short last week. Loved the movie and book. Both did and amazingly good job at explaining complex stuff in a way that was approachable by average people.
Honorable mentions worth considering: Boiler Room, Wolf of Wall Street, though not stock oriented, Glengarry Glen Ross is a great taste of the unsavoriness of business.
Too Big to Fail was interesting, but perhaps a bit too deferential to the Fed and big banks. YMMV.
