Skilda världar was a Swedish soap opera from 1996-2002 about two families in Stockholm and their friends. One rich family and one poor and about Daniel and Sandra who are from the two families and fall in love. Later in the series it is discovered that Daniel and Sandra are twins. The series goes further and further away from their story and goes more towards the hate from all characters against Rebecka who is trying to destroy the relationship between Sandra and Daniel.

Skilda världar is one of TV4's most watched shows in history and was the longest running daily soap opera in Swedish television. The series was based on the 1980s Australian soap opera, Sons and Daughters.

Serien byggde på en historia som kretsade kring två familjer, Bovallius och Toivonen, och spänningen mellan över- och arbetarklass. Tvillingarna Daniel Toivonen och Sandra Bovallius växte upp i tron att de tillhörde olika familjer, men efter att de inlett en incestuös kärleksaffär uppdagades deras släktskap med varandra.
