Are you being sarcastic? The fictional country of Wakanda has existed since the 60s along with the Black Panther
Yea, I'm a pretty big early Marvel fan. The only reason they are making a Black Panther (and thus a Wakanda) film is because they want a black hero. Black Panther isn't even a B list hero like Ant Man was. He's C list, like Guardians of the Galaxy. Marvel has a talent for spinning obscure (and not very good) comics into great films so I'm not saying it's going to be a bad film--I'm just being realistic about it's political motivations.
my dude the country's existed in the universe for ages, hence why it's connected to a stuffload of stuff in MU (like it being the only country in earth to have the metal used for capt. america's shield among other things)
I know about Wakanda, I've read the comics. The reason Black Panther was in Capt. America 3 was just to build hype for this movie, and mentions beforehand were just attempts to flesh out the "Marvel world". They are making a Black Panther movie (set in Wakanda, an African country) as outreach to black Americans. Why do you think the trailers were set to weirdly unfitting rap music? I'm not decrying this as immoral or anything, I'm just pointing out that this movie was engineered to attract black audiences into Marvel films.
