The late Chadwick Boseman took home the SAG Award for outstanding male actor in a leading role for his portrayal of Lavee Green in Netflix's "Ma Rainey's Black Bottom."

His widow, Simone Ledward Boseman, accepted the honor on his behalf.

"Thank you, God. Thank you Leroy and Carolyn Boseman," she said before thanking his co-stars and Ma Rainey's filmmakers. "If you see the world unbalanced, be a crusader that pushes heavily on the seesaw of the mind. That's a quote by Chadwick Boseman. Thank you Screen Actors. Thank you, Chad."

The drama was Boseman's final performance after he died last August at age 43. He already set a record for most SAG film nominations — four — in a single year.

It was the SAG Awards where Boseman gave one of his most memorable speeches. At the guild’s 2019 awards, Boseman spoke on behalf of the "Black Panther" cast when the film won the top award. "We all know what it’s like to be told that there is not a place for you to be featured," Boseman said then. "Yet you are young, gifted, and Black."

On Sunday night, Boseman's co-star Viola Davis won best female actor for "Ma Rainey's Black Bottom"; Yuh-Jung Youn, best female supporting actor for "Minari"; and Daniel Kaluuya, best male supporting actor for "Judas and the Black Messiah."
