Peter Billingsley is a former child actor best known for his lead role in the classic 1983 yuletide tale A Christmas Story. The film was directed by Bob Clark, a filmmaker who played a big part in Billingsley’s life. Billingsley, who directs his close friends and collaborators Jon Favreau and Vince Vaughn in Couples Retreat, explains why Clark (he died in a 2007 car accident) was an instrumental force in his life.
