Oppenheimer proves to be a truly remarkable film, one that stays with you long after the credits roll. Christopher Nolan has created something special here, offering a powerful commentary regarding the devastation of nuclear conflict. The excellent direction and outstanding acting from Cillian Murphy, Robert Downey Jr., and the rest of the cast pull you completely into the narrative, giving the sense that you’re present during events as they unfold. Despite lacking traditional action sequences, the movie maintains a gripping quality throughout its three-hour length. It's a biographical film where the outcome is already known, yet Nolan’s skill behind the camera and the actors’ impressive portrayals combine to create an unforgettable experience.
