“Now I am become Death, the Destroyer of Worlds.” No, this is not Prometheus speaking. It is J. Robert Oppenheimer, creator of the first atomic bomb and the lead character of Christopher Nolan’s new biographical drama, “Oppenheimer.” Although the movie is R-rated, it demands a wide viewership because it is an important film. Already an immense success at the box office, the film accurately showcases Oppenheimer’s academic and personal life, with an almost-scarily perfect delivery from Cillian Murphy. Emily Blunt, who plays Kitty Oppenheimer, shines as Oppenheimer’s wife, while Florence Pugh, who plays love interest Jean Tatlock, and Robert Downey Jr., who plays nemesis Lewis Strauss, deliver strong performances deserving of more screen time. Yet, at a whopping three hours and a slow pace, the picture really does not need any more time. The last hour of the movie could have been condensed to just 15 minutes. Still, when Nolan takes on a job, he does not disappoint, and the film meticulously chronicles every interaction and avoids any possible plot holes. For example, the “Trinity” bomb test sequence is truly a masterclass in filmmaking; one cannot help but think how it might be an extract from Stanley Kubrick’s “2001: A Space Odyssey.” Incidentally, Oppenheimer says the aforementioned famous line in this scene, implying his concern with the unfolding act. The end of the movie showcases the possible consequences of Oppenheimer’s invention through a jarring sequence of global nuclear destruction, leaving the audience completely terrified, and yet, thoroughly satisfied.
