Thriller Characteristics

Thrillers often take place wholly or partly in exotic settings such as foreign cities, deserts, polar regions, or high seas. The heroes in most thrillers are frequently "hard men" accustomed to danger. However, they may also be ordinary citizens drawn into danger by accident. While such heroes have traditionally been men, women lead characters have become increasingly common.
Thrillers often overlap with mystery stories, but are distinguished by the structure of their plots. In a thriller, the hero must thwart the plans of an enemy, rather than uncover a crime that has already happened. Thrillers also occur on a much grander scale. Jeopardy and violent confrontations are standard plot elements. While a mystery climaxes when the mystery is solved, a thriller climaxes when the hero finally defeats the villain, saving his own life and often the lives of others. In thrillers influenced by film noir and tragedy, the compromised hero is often killed in the process.
In recent years, when thrillers have been increasingly influenced by horror or psychological-horror exposure in pop culture, an ominous or monstrous element has become common to heighten tension. The monster could be anything, even an inferior physical force made superior only by their intellect, a supernatural entity, aliens, serial killers.
Similar distinctions separate the thriller from other overlapping genres: adventure, spy, legal, war, maritime fiction, and so on. Thrillers are defined not by their subject matter but by their approach to it. Many thrillers involve spies and espionage, but not all spy stories are thrillers. Conversely, many thrillers cross over to genres that traditionally have had few or no thriller elements.
