Dramatic Irony
Letting the audience know something a character doesn't. You watch them act without that knowledge, which creates suspense, dread or dark comedy.
Sabrina
You know who Sabrina is the second she gets off the train, and David does not. His flirting is funny and a little cruel, because you know what he ignored for years.
The Counselor
The film opens with cocaine hidden in a sewage truck and driven across the border, so you see how the trade really works. Then the Counselor, who has never done a deal, stays calm even after Westray warns that Mexican cartels are merciless. You know more than he does, and every confident line feels dangerous.
