Kevin Costner has defended casting his son in his new self-financed passion project film Horizon: An American Saga.
Costner’s 15-year-old son, Hayes, appears in the two-part film as a character named Hayes Ellison, who plays Sienna Miller’s on-screen son. Horizon is a four-part Western drama spanning the 15 years pre and post the American Civil War, written, directed and starred in by Costner.
