Interesting and has me thinking -- I wonder how Lena Horne during the original might have been as Eliza, as she is lighter-skinned than Ms. Erivo, and in things like "Show Boat" (which she wanted to play and did in abbreviated form in the film "Till the Clouds Roll By") had that whole character arc of Julie "trying to pass", and maybe someone like Lonette McKee, Julie in two Broadway productions, in an earlier production of "My Fair Lady".
