In the expansive Marvel Cinematic Universe, it’s expected that movies and their characters come out as cohesively as possible, no matter who is headlining the film. So when Ryan Coogler, director of last year’s hit Creed, was taken onboard to direct the upcoming Black Panther film, they wanted Coogler to make some suggestions for the characters introduction in Captain America: Civil War.
According to Kevin Feige, Marvel Studios president and Civil War producer, they had Coogler come in to watch the film. “We did a little bit of additional photography here and there and Ryan did a pass at a couple of those scenes. So there’s a line or two that Panther says in the movie that Ryan contributed to. [Civil War screenwriters] Chris [Markus] and Steve [McFeely] absorbed it into their draft, put their spin on it and words to it, but Ryan has started to be involved in earlier cuts of this movie.” Coogler’s Black Panther, which stars Chadwick Boseman, will hit theaters in February 16, 2018.
