A "Box Office Bomb" refers to a film that fails to generate enough revenue to cover its production and marketing costs. This often results in significant financial losses for the studio and can impact the careers of those involved in the project, including directors, actors, and producers. Factors contributing to a box office bomb can include poor marketing, negative reviews, or competition from other films. Notable examples of box office bombs include John Carter and The Lone Ranger, which struggled to attract audiences despite substantial budgets.
