xXx Movies: Release Order
The xXx franchise is a high-octane action series that follows extreme sports athlete Xander Cage as he's recruited into the world of international espionage. Known for combining death-defying stunts with spy thriller elements, the franchise delivers adrenaline-fueled entertainment with Vin Diesel's charismatic performance as the unconventional secret agent.
Note that Vin Diesel is absent from the second film, State of the Union, which instead focuses on a new agent played by Ice Cube, though the events remain connected to Xander Cage's storyline. Diesel returns triumphantly in Return of Xander Cage, which brings him back for another explosive mission. The chronological order of events matches the release order, making this the only reasonable way to watch the series.
