Washington [United States], actor, producer and director Kevin Costner, who rose to fame with his films 'The Untouchables' and 'Bull Durham', spoke about directing the film 'Horizon: An American Saga', according to The HollywoodReporter. .

Costner, who directed, co-wrote and starred in his 'Horizon' saga, stepped behind the camera for the first time since 2003's 'Open Range'.

Despite winning an Oscar for best director in 1991, Kevin Costner's Horizon: An American Saga-Chapter 1 is his fourth film as a filmmaker and his first in more than 20 years.

Costner received an Academy Award for his directorial debut, Dances With Wolves, which he followed with 1997's The Postman and 2003's Open Range; Since then, he has focused primarily on acting and producing films, but he felt that he wanted to return to the director's chair for Horizon.

"Sometimes you wonder if you can still ride a bike, but what I knew was that I believed in my story so much that it was really me who needed to direct this," Costner said. "I didn't want to leave without taking home everything I thought the movie had the opportunity to offer," he added.

He added: "There are people who are more talented than me; I'm sure there are directors who really understand the camera, but I believe in stories, and I believe in them so much that for me, I think that is reflected in my films. "I don't really surprise anyone with my technical understanding of things; I just shoot the moments and try to put my actors in places where they can be successful, and I try to film them in contexts that allow that."

Horizon is a planned four-part film series, with part two scheduled for release in August and parts three and four still in production. Costner leads a cast in a narrative about the growth and settlement of the American West in the 15 years before and after the Civil War.

When asked why he and the Western genre work so well together, particularly after his successful run on Yellowstone, the star mused: "Maybe I believe in behavior that happened a million times there and finding an authentic spin on it each time." "Don't just rely on a cliché, but dig a little deeper and put circumstances before action."

Sienna Miller, Sam Worthington, Luke Wilson, Jenna Malone, Michael Rooker and Jamie Campbell Bower co-star in the project and weighed in on Costner as a director. Worthington said: "He has a wealth of film knowledge." "He's worked with some of the greats, and I just tried to listen and take in everything he said and try to learn a little bit from him."

Wilson, noting that the role was "unlike anything I'd ever done," added: "As a kid, I'd seen him as Clint Eastwood, a Steve McQueen type, and then being directed by him, I found that attentive and sensitive that it is about what you are trying to do and what he would like you to do.

Costner has been developing the project for years, putting up $38 million of his own money to make the films when no studio would sign on and finance it. Producer Tanner Beard shared of the four-film saga that "there's nothing like this, especially not exclusive to theaters," adding that Costner is "probably the bravest person in Hollywood, hands down." Horizon: An American Saga – Chapter 1 hits theaters on Friday, according to The Hollywood Reporter.
