How theDumb Money Cast Compares to Their Real Life Counterparts

Ken Griffin, who owns most of the hedge fund known as Citadel LLC, was also a major player in the 2021 GameStop short squeeze, and, thus, a major player in Dumb Money. Here he's played by Nick Offerman, who you likely recognize first and foremost as Ron Swanson from Parks & Recreation. Offerman has proven his range in recent years, though, playing a great role in Alex Garland's underrated FX/Hulu sci-fi series Devs and Peacock's The Resort. Next year, he'll appear in both the final season of The Umbrella Academy and Mission: Impossible — Dead Reckoning Part Two.
