During film breaks, Samuel Costa, Bernardo Cunha and the actors playing the twins accidentally burned João Romeu Filho in his neck, after they ignited a firecracker in his shirt. The four actors were grounded by Helvecio Ratton.
Samuel Costa (Maluquinho) and Jair Estevão (Branca) actually argued and physically fought, similar to what is depicted in the film.
During a film break, Carolina Galvão (Carol, the girl in pigtails) cut her face after running right through a glass door at the hotel the cast and crew stayed, and was reportedly scolded by the crew. Her bruises were later covered with make up.
