A "Box Office Flop" refers to a film that fails to earn back its production and marketing costs at the box office. This often results in significant financial losses for studios and investors. Factors contributing to a flop can include poor marketing, negative reviews, or competition from other films released at the same time. Some notable examples of box office flops include John Carter, The Lone Ranger, and Cats. These films, despite high budgets and star-studded casts, did not resonate with audiences, leading to disappointing ticket sales and a lack of interest in home media releases.
