"I've faced life with people being dismissive of me," Costner told E! News. "But they can't be dismissive of ‘Horizon,’ because now it's out of their hands. And they might point to the finish line – well, this is what it did at the box office – but I know that this movie is going to play for the next 50 years."
"There's a moment in time where you want [your children] to see this movie," he said. "To understand that this is what their [ancestors] went through. It's not just a Western, it's a history of migration and what they had to do to survive. And I'm really proud of it."
During a February 2024 interview with Forbes, Costner, who previously directed the movies "Dances With Wolves," "Open Range," and "The Postman," explained his approach to filmmaking.
