What rankings movies by nominal box office receipts what important fact is overlooked?

When ranking movies by nominal box office receipts, an important fact often overlooked is inflation. Box office figures do not account for the changing value of money over time, which can significantly skew perceptions of a film's true financial success. As a result, older films may appear less successful compared to newer releases, despite potentially larger audiences and cultural impact. Adjusting for inflation provides a more accurate comparison of a film's profitability and popularity across different eras.
