The earliest thrillers date back to the 1920s and 1930s, though filmmakers had to restrict graphic content to avoid overwhelming audiences. The Bourne Identity in 1980 helped establish the modern thriller style. Common thriller subgenres include mystery, crime, and psychological thrillers, which developed from early novels like Little Red Riding Hood in 1697. Over time, audiences grew accustomed to more exciting plots, so thrillers introduced new subgenres like spy thrillers in the 1960s inspired by early Bond films.
