Just a few months after his last play “The Divine Sister” closed Off-Broadway, the playwright and performer Charles Busch has a new play on the boards. "Olive and the Bitter Herbs," presented by Primary Stages at the 59E59 Theaters, is a comedy about a cranky former actress whose apartment is haunted by a mysterious ghost who turns out to have strange connections with more than one of the play’s characters. New York Times critic Charles Isherwood tells Jeff Spurgeon about the production and Busch's career.
