Answer:
The three main types of dramatic irony are dramatic (the characters don't have information the public has), situational (what actually happens is different from the expectations), and verbal (the speaker says something different from his thoughts or that is not truth.)
The Truman Show is an example of dramatic irony since the main character doesn't know that he is being filmed.
Pride and Prejudge contains several examples of verbal irony; for example, when Darcy mentions that one of the women is not "handsome enough for him" but in the end he falls in love with her.
Harry Potter could be considered as an example of situational irony, since it is believed that he must kill Voldemort, but later, he realizes that Harry must let Voldemort kill him.
