What (who) is deliverance - definition

Deliverance is a 1972 American thriller film produced and directed by John Boorman, and starring Jon Voight, Burt Reynolds, Ned Beatty, and Ronny Cox, with the latter two making their feature film debuts. The screenplay was adapted by James Dickey from his 1970 novel of the same name. The film was a critical and box office success, earning three Academy Award nominations and five Golden Globe Award nominations.

Widely acclaimed as a landmark picture, the film is noted for a music scene near the beginning, with one of the city men playing "Dueling Banjos" on guitar with a banjo-picking country boy. It is also notorious for its brutal depiction of a sodomous rape, before which the victim is compelled to "squeal like a pig" by his attacker. In 2008, Deliverance was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant".
