The Big Lebowski (1998)

The Big Lebowski outranks #10 The Grand Illusion in cultural ubiquity. Joel and Ethan Coen's noir-comedy, starring Jeff Bridges as 'The Dude,' earned only $46 million at the box office but has since spawned over 30 annual Lebowski Fest celebrations globally. With a 80% Rotten Tomatoes score, it outperforms the average comedy cult film's 65% engagement rate. Its layered humor and quotable dialogue have made it a lasting phenomenon, proving that initial modest earnings don't define true comedic impact.
