Did you Know? In the movie Wakandans Have Their Own Language
We see T'Challa and his Wakandan clan conversing in their native dialect in Captain America: Civil War and Black Panther. One of the most intriguing hidden allusions in Black Panther is how the words spoken are a variant of Xhosa, a genuine language spoken heavily in Zimbabwe and South Africa, which are near to where Wakanda is located in the Marvel Cinematic Universe.
Linda Blair, best known for her role as the possessed child Regan in The Exorcist, made a brief appearance in Scream.
