The aim for thrillers is to keep the audience alert and on the edge of their seats. The protagonist in these films is set against a problem — an escape, a mission, or a mystery. No matter what sub-genre a thriller film falls into, it will emphasize the danger that the protagonist faces. The tension with the main problem is built on throughout the film and leads to a highly stressful climax. The cover-up of important information from the viewer, and fight and chase scenes are common methods in all of the thriller subgenres, although each subgenre has its own unique characteristics and methods.[8]
A thriller provides the sudden rush of emotions, excitement, sense of suspense and exhilaration that drive the narrative, sometimes subtly with peaks and lulls, sometimes at a constant, breakneck pace thrills. In this genre, the objective is to deliver a story with sustained tension, surprise, and a constant sense of impending doom. It keeps the audience cliff-hanging at the “edge of their seats” as the plot builds towards a climax. Thrillers tend to be fast-moving, psychological, threatening, mysterious and at times involve larger-scale villainy such as espionage, terrorism and conspiracy.
Thrillers may be defined by the primary mood that they elicit: fearful excitement. In short, if it “thrills”, it is a thriller. As the introduction to a major anthology explains:
” …Thrillers provide such a rich literary feast. There are all kinds. The legal thriller, spy thriller, action-adventure thriller, medical thriller, police thriller, romantic thriller, historical thriller, political thriller, religious thriller, high-tech thriller, military thriller. The list goes on and on, with new variations constantly being invented. In fact, this openness to expansion is one of the genre’s most enduring characteristics. But what gives the variety of thrillers a common ground is the intensity of emotions they create, particularly those of apprehension and exhilaration, of excitement and breathlessness, all designed to generate that all-important thrill. By definition, if a thriller doesn’t thrill, it’s not doing its job. ”

Writer Vladimir Nabokov, in his lectures at Cornell University, said: “In an Anglo-Saxon thriller, the villain is generally punished, and the strong silent man generally wins the weak babbling girl, but there is no governmental law in Western countries to ban a story that does not comply with a fond tradition, so that we always hope that the wicked but romantic fellow will escape scot-free and the good but dull chap will be finally snubbed by the moody heroine.”
