 In order to increase the tension between Dadinho and Marreco, acting  coach Fátima Toledo told teenager Renato de Souza (qv) (Marreco)  to bully the kid Douglas Silva (qv) (Dadinho) for 15 days. In the  scene where Marreco slaps Dadinho, Douglas Silva started crying and  threatened to abandon the movie, so the angry look he gives to  Marreco in the movie is real.
