Looks like that Book is a best-seller.

Just a few weeks after being victorious at the Golden Globes, Mahershala Ali has won the Screen Actors Guild Award for Outstanding Performance by a Male Actor in a Supporting Role.

The actor, 44, is being honored for his work in Green Book, portraying the pianist Don Shirley who hires a white chauffeur (Viggo Mortensen) for his concert tour of the Deep South in the 1960s.

“The more I’m fortunate and blessed to get to do this work, the more I realize how much I need you, all of you in this room, to draw inspiration from and get my cues as to how to go deeper,” Ali said during his speech. “And I’m just really grateful to be amongst this fraternity, amongst this fraternity of artists who have the good fortune of getting to deal with and wrestle with the human condition and trying to do that responsibility.”

In his speech, Ali shouted out his costar, Mortensen, who he also spoke highly of on the red carpet. “It started with him,” he told People TV. “Just the tone that he set, and just being the more experienced actor, the one who came onto the scene with more presence at least in our case. He was all about working together and working from a place of love and that’s what I try to work from so we were always in a certain way giving each other permission to do our best work by rooting for each other.”

The actor was nominated alongside Sam Elliott (A Star Is Born), Adam Driver (BlacKkKlansman), Timothée Chalamet (Beautiful Boy), and Richard E. Grant (Can You Ever Forgive Me?).
