But it's too difficult to create a nation like Wakanda on film.
These motherfukkers at Marvel are becoming more and more suspect IMO. They flat out refusing to make Luke Cage and Black Panther films, They refusing to put Sam Jackson on the S.H.I.E.L.D. tv show despite him wanting to be in it, they completely shytted on the War Machine character, and it's looking more and more like Falcon is gonna get the War Machine treatment in the new Cap movie.
Aint not fukking reason why Rocket Racc00n and Groot done made it to film before T'Challa. Hell it doesn't even make sense that guardians of the galaxy got made before Ant Man. You can tell motherfukkers are just picking their personal favorite properties and pushing it through development.
Just watch, we'll see Iron Fist get a movie or tv series before Luke Cage even though Luke is more popular and has a more well known (and better) origin.
