There was a huge party event happening in the same block as the shooting. This resulted in the party being heard through the cast's microphones track. The sound department had to recreate the ambient sounds and some of the dialogue on studio.
Daniela Aquino's natural eye color is green. Through out the movie, her eyes change from dark brown to light amber. No contact lenses were used to create this effect. It was all done in post-production.
The iron bars that block the exit in the back were not fixed on the walls. As a result, the cast and crew occasionally dropped them while shooting. For the scene where Henrique Larré screams through the bars, director Rafael Duarte and other crew members stood outside holding them while the actor shook them vigorously.
At the beginning of the movie, Henrique Larré's character remains tied down at the background. While attending Daniela Aquino's performance in the foreground, the crew usually forgot Henrique tied down, resulting in severe marks on his wrists.
Shot in 2 days.
