In comparison to a role like Billie Holliday, which requires the actor to go to the deepest parts of their soul, Lottie doesn't necessarily seem like a stretch for Audra, true. But where her tremendous skills lies is that she takes this role and makes it all seem so easy. There's so much rich detail in her work- the scene with Florence Mills is a perfect example of it. She's nurturing and warm, yet very funny, and then she breaks your heart as the realization passes across her face that this woman is going to be a massive star and outshine her. It's not the kind of wrenching performance that she gave in Lady Day, but that doesn't mean she isn't mining the scenes for all they're worth. Other actors could certainly play Lottie very well, but what makes Audra's performance so special is that she doesn't have to stretch at all- from the second she walks on stage, she simply is that character. Six Tonys or not, it's an excellent performance by a living legend of the musical theater and a reminder of how lucky we all are that she continues to come back to Broadway.
I am a firm believer in serendipity- all the random pieces coming together in one wonderful moment, when suddenly you see what their purpose was all along.
