It’s been twenty-five years since the film Titanic dominated the cultural horizon, yet apparently, we are still asking the same questions — about both the disaster and the film. What angle did the ship sink at? Could both Rose and Jack have fit on that door? Megan Garber takes an understandably jaded look at why we still want to know.

Time may heal all wounds, but Hollywood helps things along. For many Americans, Titanic now refers less to those 1,535 people than to just two: Jack and Rose. James Cameron’s semi-fictional film about the disaster—for a long while, the highest-grossing movie of all time—has taken on a memetic familiarity.
