Jessica Chastain will star as an activist who infiltrates online hate groups in The Savant. The fact-based eight-episode miniseries will stream on AppleTV+.

Variety reports that Chastain, fresh off her acclaimed turn as troubled country superstar Tammy Wynette in George and Tammy, will star in and executive produce the upcoming miniseries, which is based on a true story that ran in Cosmopolitan in 2019. She will play a woman known pseudonymously as "The Savant", who plunges deep into online hotbeds of hatred and bigotry, infiltrating their ranks, in order to stop large-scale terrorist attacks on the public. Andrea Stanley, who wrote the Cosmopolitan article, will consult on the series, which will be produced by Fifth Season and Anonymous Content.

After a series of TV guest appearances, Chastain broke into the mainstream in 2011 with roles in a trio of well-received films; Take Shelter, The Tree of Life, and The Help, earning a Best Supporting Actress Oscar nomination for the latter. The next year, she starred in the controversial CIA drama Zero Dark Thirty, earning her another Oscar nomination, and has continued to star in a steady stream of prestige fare, including Interstellar, The Martian, Crimson Peak, Molly's Game, and The Zookeeper's Wife.
