Big Business is a 1988 American comedy film farce starring Bette Midler and Lily Tomlin (each playing two roles). The movie revolves around two sets of identical female twins who were mismatched at birth, with one ending in a wealthy urban family (the Sheltons) and the other in a poor rural family (the Ratliffs). It was produced by Touchstone Pictures, with the plot loosely based on The Comedy of Errors (1589–1594) by William Shakespeare.
