The group of leading role actors is mostly non-actors chosen after one year of research and auditions with teenagers in Rio de Janeiro. Tainá Medina, who is 16 years old, plays the leading character Luiza and she has never acted in her life. Junior Moura, that plays João, the missing cousin of Luiza, is Felipe Bragança’s cousin in real life and only worked as an amateur actor.
Everyone in the movie is from the Nos do Morro Group, a 20 years old acting school in the slums of Vidigal. The actors from City of God also came from this place.
