What a great film this was! With Lily Tomlin and Bet Midler - two of the funniest ladies of the 1980's. Can't believe it's not remembered more.
It was obviously, an American film and was very funny - both Lily and Bet played two riles each.
The concept (and its very "concept") is following 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).
