The Russo brothers' Captain America: Civil War is coming out next year, and Anthony Mackie is happy for Marvel Cinematic Universe newcomer Chadwick Boseman to play Black Panther. They had been long-time friends and Mackie seems to indeed puts stock in having faith in Chadwick's performance, according to Comic Book Resources.
"I was very happy when I heard he got cast as Black Panther, because I knew he'd do the work to bring that character to life. It's not so much about two black actors being in a movie at the same time. It's more so about the right black actor getting that role to do the work to make it timeless, and Chadwick is that guy."
