"The Discoverers" is Justin Schwarz's feature debut, a dysfunctional family road trip tale with some quirky, unprecedented elements. Griffin Dunne stars as tired history professor, who is faced with the challenge of bringing together his disconnected family, including but not limited to his deadpan teen kids (Madeleine Martin from "Californication" and Devon Graye of "American Horror Story") and his crazed Lewis-and-Clark-obsessed father (Stuart Margolin).
