Agent J is back.

Men in Black I and II grossed nearly USD$1.1 billion combined. Now the MIB duo of Agent Jay (Will Smith) and Agent Kay (Tommy Lee Jones) is back in action with a new and exciting adventure. When the world is threatened by an evil alien, Agent Jay travels back in time to 1969, where he teams up with the younger Agent Kay to stop an evil villain from destroying the world in the future. Emma Thompson will play take-charge MIB operative Agent Oh, who is monitoring a prison breakout.
