Revealing mistake: When the two men in the car are shot with machine guns, there's a bump on each of their foreheads even before they're shot in the head. This bump was so it could disappear and reveal the bullet holes when the bullet hits their heads.

Revealing mistake: When Tony shoots Hector in the head, you can tell they stuck a red sticker to his head to simulate a bullet hole. You can tell this because there's a little bit sticking out, which is what they'd use to take it off.
