The movie adaptation of August Wilson’s play Ma Rainey’s Black Bottom (on Netflix) has been overshadowed by the death of one of its two stars, Chadwick Boseman, last August, making this his final film appearance. The command performance he gives here is a mournful reminder of how talented he was, and the stardom he had right in front of him, as he even manages to outshine Viola Davis, who’s already won one Oscar and is going to be nominated for another one for playing the title character here.

Ma Rainey was a real-life blues singer, sometimes called the “Mother of the Blues,” who achieved not just popularity but a measure of autonomy for herself in the 1920s, even writing some of her own songs and recording as early as 1923. The black bottom was a dance, and “Ma Rainey’s Black Bottom” was one of her singles – although I’m sure the double entendre wasn’t lost on audiences at the time. The film just covers the time of one recording session for that song, a fictional rendering of the day that revolves around Rainey and a talented, ambitious, and volatile trumpet player named Levee, played by Boseman.

This Rainey, at least, is a diva, demanding of her musicians and the producer alike, insisting that her nephew voice the introduction to the song, even though he has a stutter that makes the task a bit difficult. Levee, meanwhile, has dreams beyond merely playing trumpet in someone else’s band; he writes his own music, has put together his own band, and is busy trying to convince the (white) producer to pay for him to record his songs himself.

Ma Rainey’s Black Bottom, like Fences, comes across like a play on screen, with all the action taking place in just a few settings, and dialogue that never stops. The actors have to convey far more than in a typical film, but they also run the risk of overpowering it, which was the main issue I had with Denzel Washington’s performance in Fences – he dominated every scene he had without Viola Davis, and it took an Oscar-winning performance out of her just to compete.

Here, Boseman and Davis don’t share a ton of scenes, so each can take over in their own way, but neither crosses that line that made me leave the theater thinking Denzel Washington had been yelling at me for an hour and a half. Although Davis’ character is in the title, Levee is the bigger character within the film, getting – in my impression, at least – more screen time and more words than Ma Rainey does. Boseman infuses Levee with both the naked ambition of his character and the innocence required to make his decisions plausible. Levee doesn’t understand how the world works, believing in some level in a meritocracy that doesn’t exist in a world that is already predisposed against him because of the color of his skin. It requires a precise performance to ensure that this character doesn’t become ridiculous. Levee is not a fool, but he’s arrogant enough to think he’s the exception, and when the world doesn’t conform to his beliefs, the cognitive dissonance causes him to erupt in unexpected violence.

Boseman is going to win the Oscar, of course, because of his tragic death before the movie was even released, but there won’t be a plausible argument that the performance itself was undeserving. He puts Levee on a knife’s edge and holds him there for the bulk of the film, so that when he breaks, as you know he must, it works, because you’ve been waiting for him to explode. It makes Davis’ performance seem showy by comparison, although she also is likely to get (and deserve) a nomination for this role.

The story here is somewhat scant, although that seems typical of stage adaptations to screen, and Ma Rainey’s Black Bottom adheres to the play’s use of just a few settings, with the bulk of the film taking place in the recording studio or in the musicians’ room below it. That also means we don’t have much time for back story, and outside of the two main characters, everyone is pretty one-dimensional. The producer who takes Levee’s songs and promises to look them over might be well founded in history, but he’s nothing but a penny-pinching, greedy white man taking advantage of Levee’s race and ignorance here, bordering on a dangerous stereotype. (It’s worth noting, however, that Wilson and this script both changed one word of the lyrics to “Ma Rainey’s Black Bottom,” here substituting “new baby prances” for “Jew baby prances.”)

Levee’s big speech towards the end of the film broaches questions about being Black in a society that has always treated Blacks as second-class citizens when treating them as citizens at all, and even goes beyond that to an existential question about Blacks and a God who seems to have forsaken them. It is the clip I expect we’ll see when Boseman’s name is announced at the Oscars in April, because it is his biggest moment and the best pure writing in the script. I imagine this will earn a Best Picture nomination as well, but the reason to watch Ma Rainey’s Black Bottom is for Boseman’s performance – not because he’s gone, but because he’s just that good.
