Lupita Nyong'o Still 'Filled with Grief' Over Chadwick Boseman: 'I Don't Know' If 'I'll Ever Be Done Shedding My Tears'

"The grief is just the love with no place to put it, right?" 'The Wild Robot' star said at a BFI London Film Festival event on Monday, Oct. 14

Lupita Nyong'o's grief over her friend Chadwick Boseman remains, four years after his death.

During a BFI London Film Festival event on Monday, Oct. 14, the Wild Robot voice actress was shown a clip from the pair's 2018 Marvel Studios blockbuster Black Panther.

Getting emotional, Nyong'o, 41, said after a pause, "The grief is just the love with no place to put it, right?", before declining to watch another clip.

"I don't run away from the tears or the grief, you know? You just live with it. That experience will never be separate from the love that was formed," she continued.

Additionally, Nyong'o revealed she hasn't watched Black Panther since Boseman died at age 43 in August 2020, after a four-year battle with colon cancer.

"I watch this clip and I'm filled with grief and I don't know whether I'll ever be done shedding my tears from losing my friend," the Academy Award winner said. "But I'm like, we get to see him alive. And that's so wonderful."

This past August, Nyong'o — who played Nakia, a Wakandan warrior who has a romantic relationship with Boseman's T'Challa, in Black Panther — posted an Instagram tribute to her friend on the four-year anniversary of his death.

“ 'Grief never ends. But it changes,' " Nyong'o began her caption, sharing a black-and-white solo photo of Boseman and then a color snapshot of the two laughing together.

" 'It is a passage, not a place to stay. Grief is not a sign of weakness, nor a lack of faith. It’s the price of love.' —unknown," she added, concluding, "Remembering Chadwick Boseman. Forever."

Back in June, Nyong'o told PEOPLE about playing a woman with terminal cancer in A Quiet Place: Day One, saying it was "scary to have to go there" in a role where her character "is really facing their mortality, even before this apocalypse takes place, and whose life is slipping between her fingers."

And the added layer of having lost close friend and costar Boseman to cancer made it even more emotional for the actress.

"In the end, it was actually very therapeutic because I had just experienced not too many years ago the death of Chadwick Boseman, which shook me to my core," she said. "I definitely was thinking about that a lot."

"What I came to realize is that it's really important to be reminded of our mortality, because then we live life just a little more intentionally," Nyong'o added at the time. "When we think we have all the time in the world, we can really take people for granted and experiences for granted."
