Men in Black 3

Young Agent K: I can see why I recruited you. You're a good man.

Agent J: What the hell happened to you, man?

Young Agent K: I told you, it hasn't happened yet...

Men in Black 3
Starring Will Smith, Tommy Lee Jones, Josh Brolin
Written by Etan Cohen
Directed by Barry Sonnenfeld
Plot: Agent J travels back in time to prevent a young Agent K from being killed in order to save the current world.

"Not as good as the first MIB, but better than the last one. Will is still tonnes of fun and Josh Brolin is fantastic as a young Tommy Lee Jones. Delivers the fun it promises."
