Kevin Costner’s Son Finally Confirms What We Thought All Along.

Kevin Costner’s relationship with his son Hayes has deepened both personally and professionally, particularly through their work together on Horizon: An American Saga. This Western epic, which has been years in the making, became a family affair when Costner cast Hayes in the film. Though the role was a smaller one, Hayes’ character, Nathaniel Kittredge, plays a pivotal part in defending his family in the post-Civil War setting.

Kevin Costner has always been selective when it comes to involving his children in his films. He stressed that casting Hayes wasn’t just a decision to automatically give him a role. Instead, it was an opportunity to bond, allowing them to spend quality time together. Costner shared how, for two weeks, they would drive to the set together, an experience he cherished​

For Hayes, the experience was much more than just acting—it was about creating lasting memories with his father. He described the experience as thrilling, particularly given the action-packed scenes and Costner’s guidance as both a director and a father. Despite the intensity of the work, Hayes loved how his dad would switch from professional mode to “dad mode” when the day ended​

Their bond also extends beyond the film set. Both share a love for outdoor activities like fishing and sports. Hayes is an avid surfer and volleyball player, and the quiet moments spent fishing with his father remain some of his fondest memories. It’s clear that the film, in many ways, mirrors the strong, supportive relationship they’ve built over the years​.
