Variety reports that Warner Bros has cast Kiersey Clemons as the female lead in the Flash movie opposite Ezra Miller. Clemons most recently appeared in Neighbors 2, and was featured in Flash director Rick Famuyiwa’s breakout indie film, Dope. She’s also been cast in a remake of Flatliners.
Technically, WB hasn’t confirmed that the female lead is in fact Iris West, but it’s a safe enough bet that Variety ran with it in their headline.
