Jeremy Strong treated his The Social Reckoning co-stars "the way he imagines Mark Zuckerberg treats people", according to Aaron Sorkin.

The Succession star plays the Facebook founder in the sequel to 2010 drama The Social Network - which told the story of how the tech mogul started the site while he still at college - and now writer/director Sorkin has revealed keen method actor Strong stayed in character throughout the shoot.

He told the New York Times newspaper: "Jeremy does a lot of his own work. He does a tremendous amount of work before he shows up on your set. He did not speak in his own voice on the set or walk the way Jeremy walks.

"I told all the other actors in his scenes: 'Guys, he's not going to be hanging out with you at craft service. He's not going to be yucking it up with you between takes.

"He's probably not going to speak to you at all. He is going to treat you the way he imagines Mark treats the people around him. And that's what happened. You cannot argue with the results."

Jesse Eisenberg played the billionaire in The Social Network - which was written by Sorkin and directed by David Fincher - and Strong has taken over the role playing an older version of Zuckerberg in the sequel, which focuses on a 2021 whistleblower and an investigation by The Wall Street Journal into Facebook's practices.

The Social Reckoning also stars Mikey Madison and Jeremy Allen White and is due for release in October.

It comes after Strong revealed he emailed Mark Zuckerberg before he began filming The Social Reckoning because he wanted to find humanity in the 42-year-old billionaire because he felt such as a sense of "responsibility".

Speaking to America's GQ magazine, he said: "Listen, I know that he is a reviled person and not a popular person in our culture, but I do not think you should have an actor playing him who wants to set out to condemn him.

"It feels incredibly fraught to talk about the movie, to talk about Mark and being the person who is playing Mark and representing Mark in a sense to the world and to posterity; I feel an enormous sense of weight and responsibility. And listen, my job is to understand and defend his point of view and fight his fight.

"I wrote to him - I'm probably going to give Sony an aneurysm - I sent him an email. Just to say that I take this responsibility very seriously, and the veracity of it seriously, and I'm approaching it with respect."

Although Jeremy, 47, confirmed to the publication he received a reply from Mark, he declined to reveal what the Meta CEO had said to him but admitted he wouldn't have accepted any potential invite to meet him in person because he prefers to research his roles from a distance.
