Jeremy Strong's Mark Zuckerberg apparently had some defensive notes for Aaron Sorkin

The film, centered on the rise of Facebook’s founder, will now feature Strong’s portrayal instead of Eisenberg’s, marking a notable shift in the casting lineup as production moves toward its scheduled start. Strong told Deadline that he cares about Mark Zuckerberg’s view of the project, while The Hollywood Reporter quoted him saying he sees no need to apologize for his method‑acting approach, describing it as serving the material. The New Yorker observed that Strong “is not quite over it,” hinting at lingering tension.

Club piece added that Zuckerberg apparently offered defensive notes to screenwriter Aaron Sorkin, suggesting the tech mogul’s feedback entered the conversation. The articles stop short of linking any of those comments directly to the casting decision, and they provide no definitive explanation for why Eisenberg was replaced. Coverage varies on whether Strong’s statements, Zuckerberg’s notes, or separate production considerations prompted the change.

The impact on the script, Sorkin’s response, and any further adjustments to the ensemble remain undisclosed.
