Today in arts24 live from the Cannes Film Festival, Kevin Costner is presenting “Horizon: An American Saga”, a Western he directed, co-wrote and stars in with Sienna Miller. It’s been 20 years since his last appearance here on the Croisette. You might know him best for “The Bodyguard”, his Oscar-winning film “Dances With Wolves” or the TV series “Yellowstone”. The new film is a monumental project consisting of four episodes about the conquest of the American West. It’s beautifully shot, with impressive period detail and a talented cast.
