"Fight Club," directed by David Fincher and released in 1999, was initially considered a box office disappointment, grossing around $100 million worldwide against a budget of approximately $63 million. However, over time, it gained a massive cult following and is now regarded as a significant and influential film in modern cinema. So, while it may have been a "flop" in its initial release, it has since become a "hit" in terms of cultural impact and critical acclaim.
