Big Business (2004) DVD

Two sets of identical twin girls are accidentally mixed up at birth and switched - one 'pair' go to a rich family, the other to poor farmers. Years later, the poor twins head to New York for a showdown with a corporation which plans to wipe out their home town, only to find it headed by their real twin sisters. Bette Midler and Lily Tomlin play two twins each in this zany comedy.
