The production will begin previews in late November at PH's Mainstage Theater, with an opening night set for Dec. 18.
Herzog's plays — touching on the bonds of family and friends — include After the Revolution (PH), 4000 Miles (Lincoln Center Theater), The Wendy Play (ACT in San Francisco) and Belleville (Yale Rep and upcoming at New York Theatre Workshop).
Here's how The Great God Pan is characterized: "Jamie's life in Brooklyn seems just fine: a beautiful girlfriend (Goldberg), a budding journalism career, and parents (Baker and Friedman) who live just far enough away. But when a possible childhood trauma comes to light, lives are thrown into a tailspin. Unsettling and deeply compassionate, The Great God Pan tells the intimate tale of what is lost and won when a hidden truth is unloosed into the world."
Due to a scheduling conflict, Van Patten will assume the role for the previously-announced Judith Ivey. Final casting — the role of Jamie — is to be announced soon.
Baker's credits include Good People, All My Sons, Assassins and TV's "Smash" and "Girls"; Friedman is a Tony and Obie Award nominee who appeared in Ragtime, PH's The Shaggs, After the Revolution, Circle Mirror Transformation and The Heidi Chronicles; Goldberg earned her Olivier nomination for Clybourne Park in London, and currently appears in the Broadway production; Lortel and Drama Desk nominee Nobbs' resume includes Lombardi, columbinus and Four; Van Patten's Broadway credits include I Ought to Be in Pictures, Brighton Beach Memoirs and Rumors; and Wilhelmi was seen in Manhattan Theatre Source's Likeness.
The Great God Pan will continue to Dec. 30. The not-for-profit Off-Broadway Playwrights Horizons has two theatres in a complex at 416 W. 42nd Street.
