Big news for Mamie Gummer!

Meryl Streep's daughter has been cast in a recurring role for True Detective season three. Gummer will play Lucy Purcell, a mother of two in the latest installment of HBO's drama anthology series, which takes us to the American Ozarks for a crime and mystery that plays out over three decades, like a sort of macabre, twisted This Is Us. Season three will star Oscar winner Mahershala Ali, who plays Arkansas state police detective Wayne Hays.

Other cast members include Carmen Ejogo, Stephen Dorff and Scoot McNairy.

Congrats, Mamie!

We have a while until we'll see the show, as it's not set to premiere until 2019. ​​​​​​
