Which 1985 film is about an audition for a Broadway musical?

A Chorus Line (1985) is directed by Richard Attenborough and stars Michael Douglas, Terrence Mann, Alyson Reed, and Sharon Brown. What happens: Dancers from all over New York gather on the stage of a Broadway theatre in hopes of being cast, not as a lead role, but in the chorus of the next hit Broadway show. The show’s choreographer, Zach (Michael Douglas), is a gruff, no-nonsense overseer and his tough yet gentle assistant choreographer, Larry (Terrence Mann), commands the stage as he orchestrates audition routine after routine. Zach’s secretary, Kim (Sharon Brown), does her best to keep the auditions running smoothly, and all three — Zach, Larry, and Kim — attempt to deal with the arrival of Zach’s ex-girlfriend, Carrie, a former Broadway dancer who has had her fill of Hollywood and is back in New York seeking a job.
