blockbuster movie, n.All

A Blockbuster movie is a movie where they spend so much on the stars, the sets, the costumes, and the extras that they don't have anything left over for a plot.

A Blockbuster movie is a movie seen by everyone, mainly because everyone is seeing it. Good news for producers who spend liberally on special effects to win an audience; bad news for modest films that have to resort to shameless gimmicks like poignancy or memorable acting.
