Will Smith, Tommy Lee Jones and director Barry Sonnenfeld return to the kooky world of the top-secret government agents who protect our planet from hostile aliens in this third entry of the Men in Black film series.

An alien criminal kills the young Agent K in 1969, altering the timeline, changing the Agency and placing the Earth in danger. Veteran Agent J (Will Smith) must travel back in time to 1969 to before the murder and work with the young Agent K (Josh Brolin) to save him, the Agency, the Earth and humanity itself.

Flight of the Conchords' Jemaine Clement co-stars as the main baddie, "Boris the Animal".
