Variety reports that Forest Whitaker is the latest high-profile actor to sign on to Ryan Coogler’s Black Panther movie, where he’ll play the role of Zuri, an elder statesman in the Wakandan government. In the comics, Zuri was a companion and cohort to Wakanda’s former king, T’Chaka—played, briefly, by John Kani in Captain America: Captain America: Civil War—and a frequent mentor to his son T’Challa (Chadwick Boseman). He joins a cast that also includes Michael B. Jordan and Lupita Nyong’o.
