A special kind of contrast between appearance and reality – usually one in which reality is opposite from what it seems - is irony.
There are three main types of irony: verbal, situational and dramatic.
Verbal Irony includes sarcasm:
Situational Irony results when something unexpected happens:
Dramatic Irony is present when the audience knows an important detail, and remains in suspense as they wait for the detail to be revealed to the character:

When John Hinckey attempted to assassinate President Ronald Reagan, all of his shots initially missed the President; however a bullet ricocheted off the bullet-proof windows of the Presidential limousine and struck Reagan in the chest. Thus, the windows made to protect the President from gunfire were partially responsible for his being shot. (Wikipedia)
In a mystery movie or novel, the audience might know the criminal before the character discovers the truth.
In a love story, the audience could see that two people truly in love are too shy to speak to each other. The suspense results as the audience waits to see if they will ever get together.

Stores by O'Henry are famous for irony. In The Gift of the Magi, a poor woman sells her long hair on Christmas Eve to buy a gift for her husband.

Then they exchange gifts: she bought a chain for his pocket watch, and he bought a set of jeweled combs for her long hair - with money raised by selling his watch.
In Romeo and Juliet, the audience knows that Juliet is faking death, and waits to see what happens when Romeo finds her.

In films like "While You Were Sleeping" or "Mrs. Doubtfire", a false identity becomes a dramatic irony. Since we know who they really are, entertainment comes from watching the reactions of other people, and suspense builds as we wait to see how their secret will be discovered.
