Andréia Horta was originally cast as Romero's love interest Toia but dropped out, apparently because she had previously played the daughter of Alexandre Nero's character in Império (2014). Mariana Ximenes, Carolina Dieckmann and Mariana Ríos auditioned before Vanessa Giácomo was cast.
José Mayer declined the role of Zé Maria which went to Tony Ramos.
Originally titled "Favela Chic", which was changed due to the other two then current Globo series referencing Brazilian slums, I Love Paraisópolis (2015) (the Paraisópolis slums in Sao Paulo) and Babilônia (2015) (the Babilônia slums in Rio).
Alexandre Nero avoided wearing dark clothes in his scenes, so audience would not compare Romero to Nero's popular character Alfredo from Império (2014).
Unusual in the process of writing a telenovela, João Emanuel Carneiro would give titles to each script instead of just numbering the episodes. The premiere is titled "The Other Face".
Deborah Evelyn was originally cast as Nelita but switched roles with Bárbara Paz.
Murilo Benício was originally cast as Romero, but could not agree to have scenes with his ex-wife Giovanna Antonelli and disagreements with Amora Mautner. Mateus Solano, Fábio Assunção, Alexandre Nero, Eduardo Moscovis and Marcelo Serrado all auditioned before Nero was cast.
Amora Mautner would at times film scenes with hidden cameras, intending to capture different emotions in the actors.
