The Long Christmas Dinner, according to press notes, "traverses 90 years in the life of an American family as they gather around the dining room table for a holiday celebration. As generations appear, have children, wither and depart, the patterns of behavior within this comically extended family are revealed as well as the essential values in every generation."
Pullman Car Hiawatha "follows a diverse band of characters bound for Chicago during the 1930 holiday season. No ordinary train, this Pullman car allows us to eavesdrop on the thoughts and feelings of its many passengers, creating a cacophony of self-absorbed humanity."
The production also has scenic and lighting design by Harry Feiner, costume design by Marianne Custer and sound design by Quentin Chiappetta.
Performances continue through Jan. 3, 2016.
Tickets are $25 and are available through ThePeccadillo.com or by calling OvationTix at (866) 811-4111.
