Nyong'o reflected on the loss of the late actor while making an appearance on The Ellen DeGeneres Show on Tuesday, where she also dished on plans to honour Boseman in Black Panther 2.
The Oscar-winning 38-year-old actress disclosed that it was still very hard for her to come to terms with Boseman's passing, emphasizing his leadership as the thing she will miss the most about him in shooting the upcoming sequel.

Nyong'o said, "He led the movie with such compassion and just presence. When Chadwick came on set, he was present, and he brought his entire being to that movie.
"He was just so humble as well. That leadership will be missed. And he was my friend, so it's hard to think of him in the past tense. I do know for certain that he would want us to do this.
"I feel that what director Ryan Coogler has planned very much honours him and his legacy. So I feel good about going back."

The sequel to Marvel's Black Panther will obviously not include any footage of Chadwick Boseman but pay tribute to him in some way. How the plot will continue the story of the technologically advanced fictional nation of Wakanda without him as the ruler is what many will no doubt be looking forward to in the sequel.
Boseman's portrayal as T'Challa was lauded by fans and critics, with Black Panther going on to become the first superhero film to win an Academy Award.
