Mark Brokaw directs the world premiere of Wendy Wasserstein’s new play, Old Money. Characters living at opposite ends of the 20th century mingle and collide when Tobias Vivian Pfeiffer III, a professor of the history of New York, returns to the Upper East Side mansion in which he grew up to attend a party thrown by the house’s current owner, successful hedge-fund analyst Jeffrey Bernstein. John Cullum stars as Pfeiffer.
