Revealing mistakes: When Knockout Ned is yelling over the dead boy, the body is breathing.
Continuity: When Li'l Zé is makes Knockout Ned undress, Knockout Ned's shirt is already unbuttoned. But in the next shot we see him unbuttoning it.
Continuity: When Bené throws Neguinho out (after he, Neguinho, has killed his girl friend) the amount of blood on Bené's T-shirt changes
Errors made by characters (possibly deliberate errors by the filmmakers): When the Tender Trio are running away into the woods after they crashed into a neighbor's house, Shaggy says that Goose messed up his ankle but it's actually Clipper. Goose's ankle is fine.

Revealing mistakes: When Rocket walks off after having taken a picture of the Dead Lil Ze, Lil Ze's arm twitches.
Factual errors: Buscape is using a 135mm lens when he stands above a dead Lil Ze and takes his picture, but the picture that's developed is much too wide to be shot with a 135mm telephoto lens. We know it's a 135mm because, even though it does not appear in the subtitles, Buscape's boss identifies the lens in Portuguese.
Continuity: The length of the joint Lil Dice is smoking when he is hanging out with the Tender Trio changes size between shots.
Anachronisms: Lil' Ze is taken into custody by the police, Rocket runs after the police truck. The Police truck passes by a late - model Chevrolet S10, black, circa 2001. The movie is set in the seventies.
