Black Panther

During an interview with Michel Martin on the radio program "All Things Considered," Danai Gurira (Okoye) said that the language spoken by Wakandans is a real language, Xhosa, a South African language characterized by clicks and glottal stops: "It's the same language that is native to Nelson Mandela. It's from the Cape region of South Africa. And Mr. John Kani, who plays T'Challa's father, T'Chaka, he's Xhosa. And so he - they started and agreed to that language being the language of Wakanda in Captain America: Civil War (2016)."

(at around 39 mins) When Shuri gives T'challa the new shoes (called sneakers), she mentions that they absorb sound & allow silent footsteps, which T'challa demonstrates. Later in the film (at around 52 mins), T'challa runs up a ramp wearing the sneakers... accompanied by the sound of footsteps.

The Wakanda fairytale prologue and part of the closing credits are a sequence of Wakandan nanite displays.

Each credit in the closing credits has a different image to represent the cast/crew's role in the film.

In advance of the film's release in India, the filmmakers removed all references to the Hindu god Hanuman presumably to avoid generating any controversy surrounding the film.
