Columbia Pictures has released the first trailer for Men In Black 3 . And given us just a tiny bit more of a clue what to expect from the film. In short: familiar gags like the use of the neuraliser; Will Smith jumping off a very tall building and Josh Brolin doing a really, really good Tommy Lee Jones impression. The plot sees Smith's Agent J travel back in time to prevent the assassination of his partner Agent K ( Tommy Lee Jones ) in 1969 - which he must do with K's younger counterpart ( Josh Brolin ). Also appearing are Emma Thompson as another agent In Black, Jermaine Clement, Alice Eve and Michael Stuhlbarg . Please Leave A Comment- Source- Empire
