Kevin Costner lauds Sienna Miller's 'undeniable beauty' on 'Horizon' set

Kevin Costner and his Horizon co-star Sienna Miller expressed mutual admiration as they prepared for the movie's premiere on Sunday. 

British actress Miller stated she would go "to the ends of the earth" for Costner. 

In return, Costner praised her, saying, "I think she's one of our great actresses. Her outward beauty is undeniable, but she's so skilled as an actress."

The films mark a significant comeback for Miller, who was poised for superstardom two decades ago following her role in the acclaimed Layer Cake.

Recently becoming a mother—she welcomed a daughter with boyfriend Oli Green in January—Miller stunned at the photocall, wearing an open jacket and wide-legged trousers.

Kevin spent yesterday at the Carlton Hotel in Cannes conducting media interviews to promote the movie.

This film is the first of four planned installments, with the initial two set for release in cinemas this summer. 

He has been developing this story for 30 years and even mortgaged his Santa Barbara estate to finance the project.

On Sunday, Costner was honored with France's Order of Arts and Letters before walking the red carpet at the Palais. 

French Culture Minister Rachida Dati lauded him, saying, "You represent the America of wide spaces, the America of free minds, the America of cinema, and the love of culture that we share on both sides of the Atlantic." 

Referring to his iconic role in the 1992 blockbuster The Bodyguard, she added, "I will always love you."
