Although we have to wait until 2018 for a stand-alone film, Black Panther will be appear in Captain America: Civil War. Chadwick Boseman said of the character:
“He’s definitely not the life of the party in this instance. I think this is something true of the comic book character and the movie. You never quite know where he stands. There’s always a bit of concealing and mystery. So I think mysterious is more his boat. Not to say there’s not charm and he can’t be a ladies’ man and all that. It’s more like if there is humor, it’s more like James Bond.”
You can catch him in Captain America: Civil War on May 8. A stand-alone film is slated for February 2018.
