Christopher Nolan's epic biopic Oppenheimer is finally in cinemas, a three-hour treat-yourself-to-IMAX thriller featuring an absolutely incredible cast, including Emily Blunt, Matt Damon, Rami Malek and two of our guests on this here podcast, Robert Downey Jr. and The Man Who Would Be Oppenheimer, Cillian Murphy. Christopher Nolan also makes a brief appearance, and Ali sort of embarrasses himself in front of him with a QI-like fact that could well blow your mind.
