Watch the trailer for Horizon: An American Saga Chapter 1, starring and directed by Kevin Costner. In Cinemas June 28.

Academy Awardwinning visionary filmmaker Kevin Costner directs New Line Cinema’s vast “Horizon: An American Saga” Chapters One and Two, a multifaceted chronicle covering the Civil War expansion and settlement of the American West. A story of America too big for one film, this true cinematic event also stars Costner, who cowrites with Jon Baird (“The Explorers Guild”) and produces through his Territory Pictures.

In the great tradition of Warner Bros. Pictures’ iconic Westerns, “Horizon: An American Saga” explores the lure of the Old West and how it was won—and lost—through the blood, sweat and tears of many. Spanning the four years of the Civil War, from 1861 to 1865, Costner’s ambitious cinematic adventure will take audiences on an emotional journey across a country at war with itself, experienced through the lens of families, friends and foes all attempting to discover what it truly means to be the United States of America…

Costner returns to directing for the first time since his 2003 critically acclaimed hit “Open Range,” and revisits Civil Warera America, the setting for his 1990 blockbuster and directorial debut, “Dances with Wolves,” which won seven Academy Awards, including Best Picture and Best Director. He produces alongside Howard Kaplan and Mark Gillard, with Danny Peykoff, Robert Scannell, Armyan Bernstein, Charlie Lyons, Barry Berg and Rod Lake executive producing.
