Feige described Black Panther as "a big geopolitical action adventure" that focuses on family and T'Challa learning to be king,[106] with Civil War laying the groundwork for T'Challa's morality and establishing the geopolitical landscape that he would have to deal with on returning to Wakanda.[115] Moore compared the politics and humor of the film to Captain America: The Winter Soldier (2014), saying that the former would be inherent but not "preachy", and that the latter would avoid the tones of Guardians of the Galaxy (2014) and Ant-Man (2015).[10] He also said the film would be a cross between The Godfather (1972) and the James Bond films as a "big, operatic family drama centered around a world of international espionage".[19] Coogler was influenced by 1970s films such as the works of Francis Ford Coppola in that decade, as well as crime fiction. He also watched the film A Prophet (2009) for inspiration.[116] Feige called the film's story "rich in culturally relevant ideas", with Boseman indicating there were parallels to "pull from" in the film in relation to Donald Trump becoming President of the United States after Barack Obama, though Feige added that "these are conversations we were having two years ago because that is inherently the story within the comics."[43] Moore said the film does not depend on the plots of any other MCU films, but it does affect the wider MCU moving forward,[10] with Feige stating the film was "a very important" link to Avengers: Infinity War (2018) and Avengers: Endgame (2019).[106][117] Civil War did introduce the Wakandan language, based on the Xhosa language, which Boseman was taught by John Kani, who portrays T'Challa's father, King T'Chaka.[118] Additional actors portraying Wakandans in Black Panther learned the language,[119] with Coogler making the use of the language "a priority... as much as possible". Coogler tried to incorporate Xhosa "in natural and authentic situations", such as when multiple Wakandans were speaking in the presence of nonnatives and wanted to say something they would not understand.
