(performances start on Nov. 6) The playwright Douglas Carter Beane, no stranger to backstage stories, adapts this beloved MGM musical about discordant preparations for a Broadway show. This Encores! production, directed and choreographed by Kathleen Marshall, stars Brian Stokes Mitchell and Laura Osnes as the battling leads and Tracey Ullman and Michael McKean as the squabbling composer and lyricist. That's entertainment.
