50 free Oppenheimer trivia questions with answers — entertainment quiz, new questions added Aug 2026.
Christopher Nolan's Oppenheimer won seven Oscars, made nearly a billion dollars as half of Barbenheimer, and sent a generation back to the history books. This quiz covers both the film and the physicist behind it: the cast (Cillian Murphy, Robert Downey Jr., Emily Blunt, Matt Damon, Florence Pugh), the colour and black-and-white structure, the IMAX film stock Kodak invented for it, and the 57-day shoot at Ghost Ranch; and the real story of J. Robert Oppenheimer, from Göttingen and Berkeley to Los Alamos, Trinity, the Truman meeting and the 1954 security hearing. Easy questions ask who directed the film and who plays Oppenheimer. Harder ones want the biography it was based on, the New Mexico town where the Trinity scene was staged, the yield of the actual test, who wrote the score, why the film reached Japan eight months late, and when the US government finally vacated the 1954 clearance revocation. Every answer was checked against Wikipedia's articles on the film, on Oppenheimer, on the Trinity test and on the security hearing, and each question carries the sentence that backs it up. Made for film buffs, history teachers and pub quiz hosts.
