Catherine Keener and Vince Vaughn to Star in Film

The film tells the true story of Christopher McCandless, who, after graduating from college in 1992, decided to leave his life behind and take a trip to Alaska.  He spent four months camping in the wild.

Keener (Capote, The 40 Year-Old Virgin, Being John Malkovich) will play a woman who picks up the hitchhiking Vaughn (Dodgeball: A True Underdog Story, Wedding Crashers) when his car dies on the road.
