James Cameron’s next movie won’t be blue aliens—it’ll be nuclear hell. The Avatar director announced he's adapting Ghosts of Hiroshima, an upcoming book by Charles Pellegrino, into a film that he says will be as “unsparing” and emotionally devastating as Schindler’s List and Saving Private Ryan. The story follows a man who miraculously survived both the Hiroshima and Nagasaki atomic bombings—a true-life account Cameron plans to bring to screen without pulling a single punch. Cameron didn’t stop at promoting his film—he also threw shade at Christopher Nolan’s Oppenheimer, calling it a “moral copout” for glossing over the human carnage. “I want to go straight at the third rail,” Cameron said. “I’m just stupid that way.”
