The story behind the 2021 GameStop short squeeze is told in Dumb Money. Keith Gill (Paul Dano) is an amateur financial analyst, who posts about his stock investments on his YouTube channel Roaring Kitty and on the Reddit forum r/WallStreetBets. Keith makes a huge investment in GameStop stock, which is being short-sold by hedge fund managers such as Gabe Plotkin (Seth Rogen), betting on the video game store chain going into bankruptcy. However, Keithโs social media posts began a grassroots movement that resulted in GameStopโs stock unexpectedly ballooning.
Dumb Money Synopsis
Dumb Money is a film directed by Craig Gillespie (I, Tonya), based on the 2022 book

Keithโs campaign to buy up GameStop stock picks up steam, with some of the buyers including nurse Jenny (America Ferrera), college students Riri (Myhaโla) and Harmony (Talia Ryder), and even GameStop employee Marcus (Anthony Ramos). When the ballooning stock prices result in billions lost for Melvin Capital Managementโs Gabe Plotkin, he is quickly bailed out by fellow hedgefund managers Steve Cohen (Vincent DโOnofrio) and Ken Griffin (Ken Griffin). However, the bubble of the sudden growth of the GameStop stock soon bursts when the trading app Robinhood, run by Vlad Tenev (Sebastian Stan) and Baiju Bhatt (Rushi Kota), halts the ability to buy after incurring unexpected costs.
My Thoughts on Dumb Money
With its ensemble cast and Wall Street-focused plot, it can be surmised that Dumb Money is inspiring to be this yearโs The Big Short, with a dash of The Social Network, as both that film and Dumb Money are based on books by Ben Mezrich. However, one thing that made The Big Short so entertaining and accessible was how Adam McKayโs 2015 film frequently broke the fourth wall to explain complex financial concepts in laymanโs terms.
While Dumb Money does have a dialogue to somewhat explain what short-selling is, with America Ferreraโs Jenny lamenting how itโs a financial scam to make the rich richer, the film as a whole is played off as a straight-forward drama, even though some scenes have flourishes of comedy. The biggest drama in the film comes from Keith Gillโs reluctance to sell off what now amounts to millions of dollars worth of stock, since it would mean letting the hedgefund managers win, when the GameStop stock goes down again.
Like The Big Short, Dumb Money is a film that illustrates how broken the stock markets are, as they can be rigged to make the rich richer and the poor poorer. However, Dumb Money opts to show this in a relatively straight-laced manner, which results in it being a far less entertaining film than it could have been.
