Box-office bomb

In the motion picture industry, a box-office bomb or box-office flop is a film that is considered highly unsuccessful or unprofitable during its theatrical run, often following significant hype regarding its cost, production, or marketing efforts. Generally, any film for which the production and marketing costs exceed the combined revenue recovered after release is considered to have “bombed”. The label is generally applied to films that miss earnings projections by a wide margin, particularly when they are very expensive to produce. Although this often occurs in conjunction with middling or poor reviews, critical reception has an imperfect connection to box-office performance. (Wikipedia)
