To stick with the previous two fancasts, I am sticking with my choice for T'Challa/Black Panther.
Columbus Short as T'Challa/Black Panther
Columbus Short is a good actor and despite doubts, I think that he can pull of Black Panther.
Laurence Fishburne as S'yan
Fishburne is the strongest actor I've had in my trilogy and I think he could pull it off well, espcially the tragic loss of his character in this final film.
Now this one is gonna get alot of hate
Taylor Lautner as Kasper Cole/White Tiger
Taylor Lautner has background in martial arts (which he is very good) and despite the crap he gets for Twilight, he is actually a really good actor. I wanted to recreate this character a little by having him be a young man who still idolizes Black Panther and decides to become his own character, White Tiger. Black Panther knows it's dangerous and tells White Tiger to give up, but eventually during the climatic battle between Black Panther and Ulysses Klaw, Klaw nearly kills Panther before White Tiger intervenes. Thus, giving Black Panther the opportunity to kill Ulysses Klaw. Feeling the guily of Cole's death, T'Challa gives up being Black Panther and resigns as King of Wakanda leaving it to his sister.
Rutina Wesley as Shuri
Despite Rutina being older than Columbus, Shuri wouldn't be in the movie a whole lot and It was easy seeing Rutina Wesley as Shuri, the successor of T'Challa as ruler of Wakanda (no, my version does not have her become Black Panther).
Mark Strong as Ulysses Klaw
Ulysses Klaw is finally the villain in my Black Panther trilogy and I had casted Mark Strong as the character in my first fancast and I think he would be great as Klaw. He would be a very dark, sinister, personal villain for Black Panther and a great choice in my opinion to close the trilogy.
Here are the links to my previous fancasts in case you have missed them.
