Two sets of identical twin sisters for two families of the opposite spectrum of richness are born at the same time in a small rural hospital, and get mixed up in nursery, resulting in two sets of non-identical step-sister twins, who then end up growing without ever knowing the existence of their actual identical biological sisters. That is, until fate brings them together.
While it would be easy to give Big Business a hard time for its utterly implausible and silly premise, it’s more admirable to praise the director Jim Abrahams and actors Bette Midler and Lily Tomlin for pulling it all off in a believable manner.
As you’d expect from an Abrahams comedy, the humor finds its mark, and the pacing of the movie makes it easy to watch. The visual tricks of mixing all four unrelated siblings on the screen at the same time is flawless, thanks to clever choreography and the groundbreaking post production work done by Industrial Light & Magic.
