What makes a movie a “blockbuster”?
A blockbuster motion picture is a film that receives gross ticket sales of US$400 million or more internationally or $200 million or more in the United States and Canada (which acts as one market for cinema). The term was borrowed from the World War II-era bomb of the same name that flattened entire neighborhoods. The analogy is that when a blockbuster motion picture is released, competing film ticket sales are flattened by public indifference. http://en.wikipedia.
