Introduced onstage today alongside Avengers stars Robert Downey Jr. and Chris Evans, 42‘s Chadwick Boseman will be the first African-American superhero to lead a stand-alone Marvel tentpole in 2017’s Black Panther. Deadline reports that he’s signed a lucrative five-film deal that begins with 2016’s Captain America: Civil War continues through Marvel’s just-unveiled Phase 3 lineup.
The deal is said to begin with Captain America: Civil War and to include Avengers: Infinity War Part 1 and Part 2. Throw in a Black Panther solo film in 2017 and you only have one more movie in the deal… likely a Black Panther sequel if the first film does well.
