Cole called the film an historic opportunity to depict a black superhero "at a time when African-Americans are affirming their identities while dealing with vilification and dehumanization". It was important to root the film in the actual cultures of Africa, with the filmmakers consulting with experts on the region of Africa that Wakanda is supposed to be located in,[121] rooting the film "in reality first and then build[ing] out from there".[6] Coogler's vision for Wakanda was inspired by the southern African country Lesotho, a country which has historically been "an enclave, able to protect its independence because of its terrain" and was only lightly colonized by the British;[122][123] the country's traditional blankets are also featured in the film.[122] Coogler compared the rarity of vibranium existing only in Wakanda to the real-life mineral coltan that can almost only be found in Congo.[124] He wanted Wakanda to feel like a full country with multiple distinct tribes,[37] and created a project bible that detailed each Wakandan tribe to guide the design process. Special care was taken to create a futuristic look that was not alien,[10] as some of Jack Kirby's original comic designs appeared.[125]
