What was the story of ‘The Social Network’?

The 2010 original, which had David Fincher calling the shots, looked at the difficult evolution of Facebook from college ranking system created –– there’s some debate as the movie suggests –– by Zuckerberg, played there by Jesse Eisenberg.
‘The Social Network’ charts Zuckerberg and his system’s rise to ubiquity and the people who ended up suing for their share of the profits, including the Winklevoss twins and old college friend Eduardo Saverin (Andrew Garfield).
A huge hit with audiences and critics, it earned $226 million at the global box office.
How does ‘The Social Reckoning’ follow that?

Described as a companion piece to ‘The Social Network,’ Sorkin’s new script tells the true story of how Frances Haugen (Madison), a young Facebook engineer, enlists the help of Jeff Horwitz (White), a Wall Street Journal reporter, to go on a dangerous journey that ends up blowing the whistle on the social network’s most guarded secrets.
Strong is taking over the role of Zuckerberg from Eisenberg, while Mosaku’s role is unknown for now. Bill Burr (‘The King of Staten Island’) is also aboard, similarly in a mysterious role.
Where else have we seen Wunmi Mosaku?

In addition to her role in box office hit ‘Sinners,’ Mosaku has been seen in the likes of Marvel’s‘Loki’ (and she reprised her role as Time Variance Authority Agent B-15 in ‘Deadpool & Wolverine’).
Outside of those, she’s cropped up in the likes of ‘Lovecraft Country,’‘His House’ and ‘Black Mirror.’
And next up, she’ll appear alongside Amanda Seyfried in ‘The Life and Deaths of Wilson Shedd’, the forthcoming prison break thriller written and directed by Tim Blake Nelson.
When will ‘The Social Network II’ be on screens?
Sony has yet to confirm a release date for the new movie. But we’d be shocked –– shocked, we tell you! –– if it wasn’t lined up as a potential awards competitor next year.
