Men in Black 3 (stylized as MIB³ and alternatively spelled Men in Black III) is a 2012 American 3D comic science fiction-action film directed by Barry Sonnenfeld and starring Will Smith, Tommy Lee Jones, and Josh Brolin. It is the third installment in the Men in Black film series based on Lowell Cunningham's The Men in Black comic book series published by Marvel and Malibu Comics. It was released fifteen years after the original Men in Black (1997) and ten years after the first sequel Men in Black II (2002). Sonnenfeld and Steven Spielberg returned as director and executive producer, respectively. The film focuses on an old enemy of Agent K, Boris the Animal, escaping from prison and going back in time to kill the younger K, allowing his species, a ruthless alien race known as Boglodites, to attack Earth, forcing Agent J to go back in time and team up with K's younger counterpart on a mission to save his partner and the world.
Men in Black 3 received generally positive reviews from critics and became a box-office success with a worldwide gross of over $624 million. Unadjusted for inflation, it is the highest grossing film in the series.
In 2012, an alien criminal, Boris the Animal, a Boglodite, escapes from a maximum-security prison on the moon and arrives on Earth, bent on taking revenge on Agent K, who shot off his left arm and captured him in 1969. He confronts K, who is with his partner Agent J, telling him he is "already dead". J then discovers that K was responsible not only for capturing Boris, but for deploying the "ArcNet", a shield that prevented the Boglodites from conquering Earth and caused their extinction.
