If you found out today was the last day you could dance, what would you do? That's the question choreographer Michael Bennett put to a group of professional dancers. Their answers became the basis for one of the longest running shows in Broadway history:"A Chorus Line." In "Every Little Step" (2008), filmmakers Adma Del Deo and James B. Stern trace the evolution of that seminal musical from those early interviews, to the rehearsals and triumphant opening night. Interspersed through the history of the first production, a new generation of dancers audition for the revival and make a connection to the past. If you love Broadway, you'll be kicking up your heals for this absorbing documentary.
