It's not a true story. The plot and events in the movie were made up by the filmmakers to engage and thrill the audience. There's no real-life basis for it.
It's about the real - world grievances against the financial system on Wall Street. The movie likely depicts the anger of ordinary people towards the big financial institutions that were seen as responsible for economic hardships, like the financial crisis. Maybe it shows how regular individuals were affected by the actions of those on Wall Street, such as losing their jobs, homes, or savings.
One key event might be the financial losses of the protagonist due to the actions of Wall Street firms. This could be related to things like bad investment advice or being caught up in a market crash that was caused by the irresponsible behavior of big financial players.
No, it's not a completely true story. It's based on some real events and characters, but there's a lot of dramatization and fictional elements added for entertainment purposes.
