She’ll soon star in ‘The Alienist’ on TNT and in an adaptation of Sylvia Plath’s ‘The Bell Jar.’

After nearly three years at CAA, Dakota Fanning is returning to WME, The Hollywood Reporter has exclusively learned.

Fanning had first signed with WME, along with her younger sister, Elle Fanning, in 2012 after the two left their youth-focused agency, Osbrink Talent. The elder Fanning broke out as a child star with a steady string of movies, including I Am Sam and War of the Worlds.

Now just a week shy of 23, Fanning is set to play the female lead in TNT’s upcoming period thriller The Alienist, produced by Cary Fukunaga. Starring opposite Daniel Bruhl and Luke Evans, she’ll play an intrepid police secretary at the turn of the 20th century who aspires to become New York City’s first female detective.

On the big screen, Fanning can be seen next month in the Western Brimstone, which premiered at Venice last September and will be released by Momentum Pictures next month. And she will star as the troubled protagonist in Kirsten Dunst’s adaptation of Sylvia Plath’s classic novel The Bell Jar, which also will mark Fanning’s first turn as a producer.
