Every Little Step, James D. Stern and Adam Del Deo’s uber crowd-pleasing expose of the casting process for the recent Broadway revival of A Chorus Line, is both candy for confirmed theater nerds, and functioning propaganda for the uninitiated. Following the effect of infinite repetition created by the show’s on-stage mirror, Stern and Del Deo allow the structure of their film to take after the self-reflexive structure of the play. It’s a film about struggling dancers auditioning for a play about struggling dancers auditioning for a play which was initially based on the real experiences of the struggling dancers who played themselves, and the filmmakers play off this hall of mirrors beautifully.
