Running parallel to the classics, Circle Rep became celebrated for its productions of new plays, particularly those in the style that has been labeled "lyric realism," with Lanford Wilson being the leading voice of the genre.
Several of these plays went on to become major productions the following season or at other theaters, and include such original stagings as Marsha Norman's 'Night, Mother, Bill C. Davis' Mass Appeal, and William M. Hoffman's As Is.
The literary office, headed by B. Rodney Marriott and followed by Milan Stitt, was one of the few that read unsolicited scripts and plays and responded with detailed criticism.
