Othon Bastos, Luciana Braga, Marcos Caruso, Wagner Santisteban and Irene Ravache all return from Éramos Seis (1994) in new roles.
Globo TV bought the rights of the original novel to produce this series. This now prevents SBT and Record TV from broadcasting any reruns of Éramos Seis (1994) and Éramos Seis (1977), respectively. However, some actors returned in the 2019 version as to pay homage.
Final roles of Nicette Bruno and Camila Amado. Bruno died of COVID-19 complications (during the pandemic) in December 2020. Amado passed away after a pancreatic cancer battle, in June 2021.
Irene Ravache and Nicette Bruno were supposed to guest star as to pay homage to their respective versions of the story, but proved unavailable. However, their cameos turned out possible in the final episodes.
The COVID-19 pandemic had already struck Brazil by the time shooting was to end. Rewrites and reducing of the crew were required. Filming was finished two days after Globo TV shut down production completely.
