The first trailer for
Men in Black 3 was unveiled online.
Starring
Will Smith,
Tommy Lee Jones, and
Josh Brolin, the third installment is directed by
Barry Sonnenfeld from a script by Etan Cohen.
Agent J. (Smith) “time jumps” back to 1969 and lands in an office chair smack down in front of Josh Brolin, who plays the young Agent K (Lee Jones).

Here's the synopsis from the film:
In Men in Black 3, Agents J (Will Smith) and K (Tommy Lee Jones) are back… in time. J has seen some inexplicable things in his 15 years with the Men in Black, but nothing, not even aliens, perplexes him as much as his wry, reticent partner. But when K's life and the fate of the planet are put at stake, Agent J will have to travel back in time to put things right. J discovers that there are secrets to the universe that K never told him — secrets that will reveal themselves as he teams up with the young Agent K (Josh Brolin) to save his partner, the agency, and the future of humankind.
Alice Eve,
Emma Thompson, Rip Torn,
Johnny Knoxville, and
Jemaine Clement are also featured in the film.
Men in Black 3 opens May 25th, 2012.
