In an Instagram post, Lee said he was sad to announce Byrd's death and recalled how the actor "did his thang" in his films including "Clockers," "Chi-Raq," "Bamboozled," "He Got Game" and "Da Sweet Blood of Jesus," among others.
"May we all wish condolences and blessings to his family," Lee wrote. "Rest in peace, Brother Byrd."
Lee also shared some of his favorite scenes with Byrd from "Clockers" and "Bamboozled."
Byrd, also a stage actor, was nominated in 2003 for a Tony for his performance in the Broadway revival of "Ma Rainey's Black Bottom," co-starring Whoopi Goldberg and Charles S. Dutton.
Oscar-winning actor Viola Davis tweeted: "Oh no!!! 2020! Whaaattt!!!"
"Loved working with you Byrd," she wrote. "What a fine actor you were. So sorry your life ended this way. Praying for your family."
Byrd was a "brilliant dancer, actor, and friend," Elisabeth Omilami, a fellow actor and community activist, told WXIA-TV in Atlanta.
"He was a special person whose personality filled up the whole room when he entered you knew he was there," she said. "He fought his way through this very racist and difficult Hollywood system and was able to maintain a career through it all."
She said Byrd had just recently finished his last film, "Freedom's Path," with her husband, actor Afemo Omilami.
Actor Lori Petty tweeted: "What a man, what a talent ... what a crazy loss."
