American Assassin explores themes of vengeance versus duty. It asks whether a "broken" person can be turned into a functional tool for national security. While critics pointed out that the film occasionally falls into standard genre tropes, fans of the spy-thriller genre praised its unflinching violence and the stakes of its nuclear-threat plotline.

The story begins with a harrowing personal loss. Mitch Rapp (Dylan O'Brien) witnesses the death of his fiancée in a terrorist attack on a beach in Ibiza. This trauma transforms him from a grieving student into a self-trained, obsessive vigilante. His single-minded pursuit of the terrorists catches the eye of the CIA, leading him to a black-ops training program headed by Cold War veteran Stan Hurley (Michael Keaton).

The 2017 film American Assassin , directed by Michael Cuesta, serves as a high-octane origin story for Mitch Rapp, the popular character from Vince Flynn’s best-selling novel series. Blending personal tragedy with international espionage, the film attempts to carve out a space for itself alongside iconic franchises like John Wick and Jason Bourne .
