Miller's co-star, Sam Worthington, also shares his admiration for Costner's approach to filmmaking and the message conveyed through "Horizon." "I just like working with directors that take risks and are trying to challenge themselves in storytelling," Worthington remarks.
"With this, it's a more traditional way of filmmaking," he continues. "But at the same time, he's not telling a plot-driven story. He's taken an almost like a novelistic approach to the journey of these characters – to this central character, which is the town of Horizon."

Worthington believes that Costner's vision extends beyond the historical setting of the Western genre. "I think that Kevin is telling a story that shows that there was a lot of hope in how America was formed," Worthington explains. "And therefore, if [there's] this hope in the formation of America, then maybe there's hope in the continuation of America – whether it's a Western or science fiction."
"Good movies explain to us how we are now," he adds. "And so, if that's his message, I think that's a great message for the America that we're in."
