The limited series “Fosse/Verson,” which starts Tuesday on FX, spins and arches its way through the relationship between Bob Fosse and Gwen Verdon. Fosse was a dancer, choreographer, director and filmmaker, who would win nine Tony Awards. Verdon, who married him in 1960 and continued to work with him after they separated in 1971, was the greatest comic dancer Broadway ever fell for and won four Tonys of her own.
Created by some more big Broadway names — Thomas Kail and Lin-Manuel Miranda, of “Hamilton,” are executive producers, Steven Levenson, who wrote the book for “Dear Evan Hansen,” is the showrunner — the series assumes a thorough knowledge of mid-century Broadway and beyond. Here’s a cheat sheet to who’s who and what’s what.
