The curtain is about to rise on the first production of Roundabout Theatre Company’s fall season, and to celebrate new beginnings, the stars and creative teams off three forthcoming productions gathered on September 10 for a kick-off party at the American Airlines Theatre. Roger Rees, Mary Elizabeth Mastrantonio and the cast of The Winslow Boy joined in celebration with the stars of off-Broadway’s Bad Jews and the playwright of Roundabout Underground’s Too Much, Too Much, Too Many. Other members of the Roundabout family were also in attendance at the shindig, which included a heartfelt speech from artistic director Todd Haimes.
