Continuity mistake: When Machete is picked up by Booth in the S-class, the car changes from an S500 to an older generation S-class, and then switches back for the rest of the film. The footage was from the trailer being edited in.
Continuity mistake: When Machete mounts the minigun to the motorcycle in the big fight scene at the end of the movie, it's just the gun barrels and breech on a plate between the handlebars, with no ammo feed. When he's in midair and firing, there is a very visible ammo feed chute going into the side of the gun (as there should be). In the next frame, he lands and gets off the bike, and again it's only the gun/breech assembly, no ammo feed.
Continuity mistake: After Machete's failed sniper shot on the roof-top, he is chased onto a rooftop where he kills a bunch of people. After he has killed everybody a splat of blood randomly appears on the ground.
Trivia: This is the second time that actor Danny Trejo has played a character named Isador "Machete" Cortez, the first time being in "Spy Kids." It's debatable whether or not they are the same character.
Padre Benito del Toro: I absolve you of all your sins. Now get the fuck out.
Machete: Machete don't text.
Padre Benito del Toro: It's not safe for you to be here.
Machete: I'm not looking for "safe."
Padre Benito del Toro: No, I mean it's not safe for me for you to be here!
