Men in Black 3

“Back in time.”

Agent J (Will Smith) has spent fifteen years with the Men in Black and still can't explain his partner, Agent K (Tommy Lee Jones), who never says where he came from or why. Then K is gone from the present as though he was never there, and J learns the reason is tied to Boris The Animal (Jemaine Clement). To save his partner and the planet, J has to go back in time and find the young Agent K (Josh Brolin).
