Big Business is a 1988 American comedy film starring Bette Midler and Lily Tomlin, each playing two roles, as sets of identical twins mismatched at birth. The nature versus nurture farce adapts The Comedy of Errors, but with female siblings in contemporary society: one of each twin being reared in a wealthy urban setting, while the others grew up in a poor rural environment.
