Observers say that welcoming of guests including Cate Blanchett, Monica Bellucci and Spike Lee is a move to raise pontiff’s profile

A host of Hollywood celebrities will meet Pope Leo on Saturday, a gathering Vatican observers say is aimed at giving some star power to the pontiff, who is the first US pope in the history of the Catholic church.

Cate Blanchett, Monica Bellucci, Chris Pine and Adam Scott are among the actors who will join a special audience with Leo at his Apostolic Palace residence, along with the Oscar-winning directors Spike Lee, George Miller and Gus Van Sant.

The Vatican said in a statement this week that the pope “has expressed his desire to deepen dialogue with the world of cinema … exploring the possibilities that artistic creativity offers to the mission of the church and the promotion of human values”.

Before the audience, the Chicago-born pontiff revealed his four favourite films: Robert Wise’s The Sound of Music, Frank Capra’s It’s a Wonderful Life, Robert Redford’s Ordinary People and Roberto Benigni’s Life Is Beautiful.
