The sequel to David Fincher’s The Social Network, The Social Reckoning, is coming on October 9, and with it, a new star stepping into the shoes of its main character, Mark Zuckerberg. That man is Succession’s eldest boy himself, Jeremy Strong. "He simply did not want to be conflated with Mark Zuckerberg anymore; he has his problems with the guy," Sorkin explained. We won’t have to wait long to see how all of this preparation has contributed to the success of The Social Reckoning, as it hits theaters on October 9. Whether Mark Zuckerberg will sit down to watch it is a completely different question.
