In the final fight scene between Louis and Silverio, Louis' students are clapping and starting up the "Paranaue" chant when he is almost defeated. In several shots after it starts, the students are seen in the background among the fight circle, not clapping or chanting at all, yet it can still be heard.
After Louis damages the car shop, he is chased throughout the neighborhood by the Brazilians and the Jamaicans. He is eventually cornered on someone's property and hiding in the midst of hang-drying laundry. One thug closing in on Louis, can be seen flipping a switchblade and saying something in Poturguese. When the camera shows his face, it's clear that the actor's mouth is not moving even those words are still being spoken.
