Machete (2010)

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.

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!

Trivia: During the big battle at the end, when one of the vigilantes is crushed under a bouncing low rider, you can hear the Wilham scream.
