Chadwick Boseman has revealed he got into a row with Marvel about the Wakandan people of Africa using British accents.
The studio was initially convinced that an African accent would be "too much for the audience to take in" and wanted to alter their dialect so that they spoke with an English twang, but Chadwick Boseman - who starred as T'Challa in the widely acclaimed film- fought against bosses because he felt it was important to keep the authenticity throughout.
Speaking on The Hollywood Reporter's Awards Chatter podcast, he said: "They felt that [an African accent] was maybe too much for an audience to take. I felt the exact opposite.
"Like if I speak with a British accent, what's gonna happen when I go home? It felt to me like a dealbreaker. Having gone through similar situations before where I was willing to, like, stand up for it I was like, well, here we go again.
So for them I don't think it was that deep, I think it was an opinion. No, this is such an important factor that if we lose this right now what else are we going to throw away for the sake of making people feel comfortable? So yes that was a huge thing -- once we decided to do it, we went for it."
