Chadwick Boseman, who plays its king T'Challa and (more importantly) the Black Panther, tells the BBC that getting Wakanda right was the most important thing.
"This is fantasy and we have to create a culture," he says. "It's not necessarily because it's the first time we're seeing a black superhero; I think it's because we have to define what Wakanda is.
"It can't be some generalised version of what the country is or the accent.
"It can't be generalised in why we wear certain clothing or why we have the number of tribes we have - what are those tribes?
"We have a river tribe and a border tribe for example."
