As part of a Marvel films presentation at CinemaCon in Las Vegas, it was revealed that actress Letitia Wright will play Shuri, T'Challa's sister, in Black Panther. Wright's casting has been known for some time, but as with many actors in the film, her role was, until now, undisclosed.

In comic books, Shuri is T'Challa's sister and has served as both monarch of Wakanda and as the Black Panther. She has been an integral part of Ta-Nehisi Coates' acclaimed ongoing run on Black Panther.
Black Panther is due out in theaters February 16, 2018.
