Jeremy Strong reportedly stayed in character as Mark Zuckerberg throughout filming Aaron Sorkin’s forthcoming film The Social Reckoning, using the Meta founder’s voice both on and off set. The account highlights Strong’s well-known method approach and suggests his performance will be a major point of interest when the film is released.

In a GQ profile, Strong said he treats a character’s voice as an essential part of making them feel like a real person, and was interviewed while using a Polish accent for another role. Friend Bradley Cooper said he enjoyed speaking with Strong in character, while the article notes that Strong’s preparation is chiefly based on intensive research; The Social Reckoning is due in cinemas on 9 October.
