Kevin Costner's 'Horizon: An American Saga' received a seven-minute standing ovation at the Cannes Film Festival.

Costner promised three more installments in the franchise.

The Western epic is directed, produced, and stars Costner, focusing on the American West expansion from various viewpoints.

Despite some walkouts over its length and storyline, Costner's performance and a sneak peek at the next installment were well-received.

The star-studded ensemble cast includes familiar faces, and Costner financed the project with $38 million of his own money.

The film is set for a U.S. release on June 28 and is part of a multi-chapter series, with ongoing production for Chapter 3.

Costner's departure from 'Yellowstone' to focus on 'Horizon' has drawn attention.

Costner plans to discuss the project on the Awards Chatter podcast.

The release strategy for the film poses risks if the initial installment fails to attract audiences, but Costner remains dedicated to his vision for the franchise.
