Mine has to be Boiler Room. Wolf of Wall Street takes all of its terminology and idea from the movie. Boiler Room is just a classic cast, plot and outcome. Margin Call is for nerds, American Psycho is about a psycho not about Wall Street, Wall Street (the real one) is probably the best just because of Michael Douglas. The Big Short is completly misguiding as well as Too Big Too Fail which portrays Hank Paulson as a hero.
