Black Monday is an American historical dark comedy television series created by Jordan Cahan and David Caspe that premiered on January 20, 2019, on Showtime.

The series stars Don Cheadle, Andrew Rannells, Regina Hall, Casey Wilson, and Paul Scheer, and follows the employees of second-tier Wall Street trading firm the Jammer Group during the year leading up to "Black Monday", the day when international stock markets crashed in 1987.

It's the story of how a group of outsiders took on the blue-blood, old-boys club of Wall Street and ended up crashing the world's largest financial system, a Lamborghini limousine, Don Henley's birthday party and the glass ceiling.

Monroe plans to use Blair to execute an underhanded business deal that involves buying out Tiffany's family company, Georgina Jeans.

The resulting backdoor deals, personal conflicts, and the journey of a particular pin create an increasingly convoluted mess as Black Monday approaches.

The pilot was set to be directed by Canadian comedians Seth Rogen and Evan Goldberg, who were also to serve as executive producers along with Caspe and Cahan.

The website's critical consensus reads, "Black Monday zips with irrepressible style and a seductively stacked cast of charismatics stars – but this Wall Street odyssey is too preoccupied with flash to ferment its needed substance.
