This week, a special show for the festive season on art with a message. First, the king of the blockbuster, James Cameron on his new film and the horror of nuclear war.

Then, a conversation about "Kyoto," a hit play on both sides of the pond, finding humor and hope in climate negotiations. Also, a punk take on feminism with artist, Linda and the Spanish master, Pedro Almodovar on delivering beauty and vibrancy in even our toughest moments.

Plus how we use art to understand each other as Hong Kong staged an opera about Trump, and from the archive: a New York Opera about Nixon in China, and finally unveiling a mural with special meaning at St. Patrick's Cathedral in New York.
