Senator Lindsey Graham's sudden death prompts Jon Stewart to dive into the gerontocracy problem in Washington, D.C., Trump's backhanded tribute to his deceased "friend," the bucket list that Graham never got to complete, and how Mitch McConnell somehow managed to outlive his colleague from South Carolina. "People want to go on this journey with us, let's give them a reason to believe." Oscar-winning director, writer, and producer Christopher Nolan sits down with Jon Stewart to discuss his new film, "The Odyssey." They talk about "Oppenheimer" paving the way for "The Odyssey" to be made, Nolan's process of constructing movies through diagrams and structures, his embrace of the fantastical while showing respect to the film's source material, and finishing ahead of schedule despite filming with an IMAX camera in three-minute increments.
