Men in Black 3 (stylized as MIB³ and alternatively spelled Men in Black III) is a 2012 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 trilogy 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. In the film, Boris the Animal, an old enemy of Agent K, escapes from prison and goes back in time to kill the younger K in order to allow his species, a ruthless alien race known as Boglodites, to attack Earth. This forces 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.
