Located in an area of approximately 5,000 sq. m., where today stands a shopping mall, "Coroado" was the second outdoor city set built for a Brazilian telenovela, and it had eight streets, a square, a city hall, a police station, a church, an inn, a pharmacy, bars and a grocery store. During a flood in Rio de Janeiro, a confused helicopter news team took aerial shots of the destroyed sets, and the images eventually, and mistakenly, ended up as newspaper headline of a real event in a neighborhood.
Janete Clair was inspired by Corbett Thigpen and Hervey M. Cleckley's book "The Three Faces of Eve" (1957), John Steinbeck's novel "The Pearl" (1947), Fyodor Dostoevsky's final novel "The Brothers Karamazov" (1880) and Bertolt Brecht's play "Mother Courage and Her Children" (1939).
During production, Regina Duarte (Ritinha) became pregnant with her first son André, so, her character was rewritten to include the pregnancy and to give birth to a baby girl, named 'Gabriela' in the plot. In 1973, working in another telenovela, Duarte had a daughter, whom she named Gabriela Duarte. In 1995, already a professional actress, Gabriela played the character of 'Ritinha' in this telenovela's remake.
