Spy films show the espionage activities of government agents and their risk of being discovered by their enemies. From the Nazi espionage thrillers of the 1940s to the James Bond films of the 1960s and to the high-tech blockbusters of today, the spy film has always been popular with audiences worldwide. Offering a combination of exciting escapism, technological thrills, and locales, many spy films combine the action and science fiction genres, presenting clearly delineated heroes for audiences to root for and villains for them to hate. They may also involve elements of political thrillers. However, there are many that are comedic (mostly action comedies if they fall under that genre).
