Blockbuster

Blockbuster, as applied to film or theater, is a very popular and/or momentarily successful production. The term was originally derived from theater slang referring to a particularly successful play; in film industry parlance it has come to refer to a film that earns an amount of revenue exceeding some threshold. In a looser sense, it may mean any big-budget Hollywood movie with famous stars that dominates public attention, even if the movie is a financial dud.
