Christopher Nolan has been elected to lead the Directors Guild of America. He calls it "one of the greatest honors" of his career. The guild represents around 19,500 film and TV directors in the U.S. and abroad. Nolan, known for championing the theatrical experience, will take over from Lesli Linka Glatter. He plans to work with her and the board to secure creative and economic protections for members. Nolan's recent film, "Oppenheimer," was a box office hit, grossing over $976 million worldwide. His next project, an adaptation of "The Odyssey," opens July 17.
