Kevin Costner's Ambitious Western Saga 'Horizon' Nears Debut

The four-part film series, self-financed by Costner, explores America's westward expansion and premieres June 28.

Costner received a key to the city of Irving, Texas, during promotional events for 'Horizon.'
The series spans a 15-year period of pre- and post-Civil War American history.
Costner invested $38 million of his own money into the project.
Early reviews are mixed, but the film received a standing ovation at Cannes.
Costner's son Hayes makes his acting debut in the series.
