I'm definitely going to try and find the art book for this film and get a copy for myself. I feel like this is going to be a lot of peoples' first introduction to the mere concept of Africa having a pre-colonial history that involves distinct and diverse cultures with a variety of interesting and sophisticated art styles, architecture, writing systems, etc., and that excites me very much. Roots was a milestone in that it really pushed slavery and black Americans' connections to Africa into the cultural sphere, and I hope that Black Panther is able to have this similar effect in not just presenting ideas of African modernity and futurism, but also showing off versions of indigenous cultures that existed in the pre-colonial age, extending the narrative further back than just connections related to slavery.
On that note, because my sisters binge on Disney Channel, I wonder what kind of Black Panther promotional material they'll be doing on said channel. From what I've seen of other MCU promo stuff on there, they usually tend to have the more "fun" characters and elements involved to try and sell the film to little kids (primarily girls) -- granted, all three MCU films this year were pretty light and "fun" in tone (and one of them involved Zendaya) so they were easier to sell to kids in that sense -- so I can't necessarily imagine them considering Chadwick as "fun" enough, as much as I like the guy. My bet would be on Letitia Wright making appearances, perhaps together with her on-screen brother to sell the sibling relationship.
