These three films were all based on actual events.
I recently watched Dumb Money about the GameStip short squeeze. I enjoyed it but think The Big Short which is about the financial crisis of 2007-2008 is much better. The Big Short does a great job of explaining financial concepts directly to the audience.
The Wolf of Wall Street informed young people about what quaaludes were. The drug was last sold in 1985. (That’s around the only time I tried it.)
