Homer's Odyssey was an early influence on the thriller genre. One of the earliest thriller films was Safety Last! (1923), and directors like Hitchcock and Lang helped establish the modern thriller genre in the 1920s-1930s. Thrillers remain a popular genre at the box office today, including subgenres like crime thrillers, sci-fi thrillers, and horror thrillers. Characters in thrillers often include criminals, stalkers, victims, and characters with dark pasts intended to create suspense and anticipation in the narrative. Thrillers aim to disrupt the equilibrium and keep audiences guessing through complex plots and twists until questions are answered at the end.
