A lot has changed since David Fincher's The Social Network hit theaters in 2010.

That film examined the founding and meteoric rise of Facebook, as well as CEO Mark Zuckerberg's (Jesse Eisenberg) tumultuous relationship with co-founder Eduardo Saverin (Andrew Garfield). However, Facebook's trajectory since then, from its data breaches to Zuckerberg cozying up to President Donald Trump, has generated enough material for several more movies.

Enter The Social Reckoning. Touted as a "companion piece" to The Social Network, the highly anticipated drama is written and directed by Aaron Sorkin, who won an Academy Award for his Social Network screenplay.

The film dives into the collaboration between Facebook employee-turned-whistleblower Frances Haugen (Anora Academy Award winner Mikey Madison) and Wall Street Journal reporter Jeff Horwitz (The Bear Emmy winner Jeremy Allen White), which led to 2021's "The Facebook Files." That investigative series used internal documents to uncover Facebook's awareness of its harmful impacts, from teens' declining mental health to political misinformation.

The Social Reckoning finds a new Mark Zuckerberg in Succession's Jeremy Strong, who takes over from Eisenberg. The film's first teaser trailer sees Strong sporting Zuckerberg's unfortunate Caesar cut and nailing his distinctive voice to an uncanny degree.

The teaser also uses a few brief notes from Trent Reznor and Atticus Ross' Academy Award-winning Social Network score, but the pair, like Fincher and Eisenberg, are not returning for The Social Network's follow up. Alexandre Desplat will score the film instead.

The Social Reckoning also stars Wunmi Mosaku, Betty Gilpin, Billy Magnussen, and Bill Burr.

The Social Reckoning hits theaters Oct. 9.
