The cast of Marvel's Black Panther continues to grow, as we get closer to the early 2017 production start date. Letitia Wright signed on last month as Serita. Today, we have a new casting call which finds Marvel seeking actors to play a number of different types of Wakanda characters, including actors of Korean and Filipino descent. There is also another type of character the studio is seeking, which may hint that T'challa is coming back to America.

Georgia Casting Calls posted a cast listing last week, with the final listing for "CIA Agent Types with WEAPONS experience." The studio is looking for clean cut men and women of all ethnicities between the ages of 30 and 50 who have real weapons experience, who will be needed at the end of January. This could hint that either T'challa will be returning to America, or that the CIA may raid his homeland of Wakanda, but no specific details were given about what scenes these characters will be needed for.

We first met Chadwick Boseman's T'challa in Captain America: Civil War, which featured a post-credit scene where Steve Rogers (Chris Evans) had brought Bucky Barnes (Sebastian Stan) to a secret facility in Wakanda, hiding him from the authorities. It's possible that the CIA may have found out where Bucky was brought to, which is why these CIA agent characters are needed. As for the African characters listed in this casting notice, there are several different types the production is looking for.
