The Main Stage season at the Williamstown Theatre Festival in Massachusetts will conclude with a "mini-festival" celebrating the "art of theatre and storytelling."

The three-show line-up began Aug. 14 and will run through Aug. 25. Recently added to the cast is actor Andrew McCarthy, who will star in A Distant Country Called Youth, adapted from the letters of Tennessee Williams and directed by Steve Lawson.

McCarthy was seen on Broadway in Side Man and at Hartford Stage in numerous classics, including a recent touring production of The Glass Menagerie, starring Elizabeth Ashley.

A Distant Country Called Youth looks at the early correspondences of a young Tennessee. Lawson adapted the letters from "The Selected Letters of Tennessee Williams, Vol. 1: 1920-1945." Aug. 20-24 are the dates.

The festival began with For the Pleasure of Seeing Her Again, starring Olympia Dukakis, directed by Carey Perloff. Dukakis, who has been acting at WTF for years, will play Nana, a "witty, wild soul." The piece was written by French-Canadian playwright Michel Trembley. Perloff is the artistic director of the American Conservatory Theatre in San Francisco, where Dukakis has acted. Still to come is Lackawanna Blues, the well-traveled memory piece by and starring Ruben Santiago-Hudson, which will play Aug. 21-13 and Aug. 25.

Lackawanna Blues has gone from an Obie-winning run at the Public Theater in Manhattan to celebrated stays in several cities across the nation. Santiago-Hudson has appeared in every incarnation. Loretta Greco will direct.
