Will Smith and Tommy Lee Jones reprise their roles as Agents J and K in this third instalment of the sci-fi action comedy. Agent J (Smith) has long been every bit as perplexed by the perpetually-surly countenance of his older partner, Agent K (Jones), as he has been by the variety of aliens the pair are charged with keeping under control. However, when alien forces assassinate K with such extraterrestrial efficiency Agent J seems to be the only person to believe that K hasn't been dead for 40 years, the younger man is at a loss and determines to get his partner back. With the aid of a terrifying 'time jump', Agent J travels back to MIB's early years in the 1960s. Here he hooks up with a younger Agent K (Josh Brolin) and attempts to prevent his death and change the course of history. Will he also learn a thing or two about the secrets of the universe the older K kept so close to his chest?

Sequel to the successful sci-fi-cop, comedy-drama. Some four years after the Men in Black averted a major intergalactic disaster, K (Tommy Lee Jones) has returned to a civilian life, working as a postman and quite unaware of his former heroics alongside Agent J (Will Smith). But when J uncovers a secret alien plot organised by the seemingly seductive Serleena (Lara Flynn Boyle) he has to call on K again. Unfortunately K has no memory of his former role as 'Saver-of-the-World', but somewhere in his head is the expertise that can save the Earth, if only J can get him onside in time.

After chasing a fugitive with an advanced alien weapon, New York cop James Edwards (Will Smith) finds himself recruited to the MiB, a top secret agency in charge of alien immigration on Earth. He is partnered with K (Tommy Lee Jones), and sent to investigate an alien prediction of the end of the world. They have to track down a hostile alien life form currently wearing the human skin of a country hick named Edgar.
