Even before Winston was a student at Yale, Nyong'o was assigned to show him around the campus. They remained friends throughout college as part of the school's drama program and even went to see the first "Avengers" movie together, long before landing their Marvel roles as M'Baku and Nakia.
"He was extremely tall, and he has quite the presence — but he was also very internal and pensive," Nyong'o told The Hollywood Reporter.
She added: "He was on edge because he was auditioning to get into the school, but he also had a very clear idea of who he wanted to be in the world."
After appearing in 2018's "Black Panther," Duke and Nyong'o teamed up again the following year for Jordan Peele's psychological thriller "Us."
