Writer Ana Maria Moretzsohn and a great part of the cast are reunited from Floribella (2005), including that series' star Juliana Silveira. She again portrays a singer.
Juliana Silveira wrote Nina/Lucky Star's songs herself. Nina's single "I Got What You Need" samples Nelly Furtado's "Promiscuous", which was a hit at the time.
Juliana Silveira passed on the role of Bebel (a prostitute, which went to Camila Pitanga in Globo TV's Tropical Paradise (2007) ) to play Nina in this series. She reportedly thought the role of Nina was more appropriate to her fans from Floribella (2005), a children's show. "That wasn't the right time, also post-Floribella (2005). I can play prostitutes in the future, if they ask me. But right now, I'd be getting rid of that two-year work."
