As Ben Platt said to Cynthia Erivo, as she joined him onstage in June during a performance of his Live at the Palace stint at Broadway’s Palace Theatre, “It was very clear then that you were destined to the stratosphere.”Platt was referring to a period nearly a decade ago, when Erivo starred in The Color Purple on Broadway, while he starred across the street in Dear Evan Hansen. Erivo is, indeed, well on her way to stratospheric celebrity, three-quarters of the journey to being queened an “EGOT,” shorthand for someone who has won an Emmy, Grammy, Oscar, and Tony.
