60 free Killers of the Flower Moon trivia questions with answers — entertainment quiz, new questions added Aug 2026.
This Killers of the Flower Moon trivia quiz covers all three layers of the story: Martin Scorsese's 2023 film, David Grann's 2017 book, and the real killings of wealthy Osage people in 1920s Oklahoma that both are built on. The film questions get into how DiCaprio talked his way out of playing the FBI agent, the Zoom call that won Lily Gladstone the part, the composer the film is dedicated to, the Cannes ovation, the ten Oscar nominations that produced no wins, and the closing radio-drama scene in which Scorsese himself reads Mollie's obituary. The history questions go to the sources behind the script: where the Osage were relocated from, the year oil was found, the guardianship law that made the crimes possible, how Anna Brown's death was first explained away, the bomb at the Smith house, the hitman's price for killing Henry Roan, the paroles, the pardon and the 2011 settlement with the U.S. government. Roughly a third of the questions are answerable by anyone who saw the film once; the rest reward people who read the book or went down the Osage County rabbit hole afterwards. Every answer was checked against encyclopaedia entries on the film, the book, the murders and the people involved before it was published.
