A thriller film is a genre that aims to excite and delight audiences through building tension and keeping viewers in suspense. Rather than relying on other genres like horror or action, thrillers generate interest through puzzling and unexpectedly changing plots that keep audiences on the edge of their seats trying to figure out what will happen next. Effective thrillers use techniques like fast camera shots, long shots, mid shots, close-ups and extreme close-ups to make the narrative seem more interesting and convey a clear understanding of the story in a brief way to gradually build tension through numerous scenes and maintain a sense of suspense throughout.
