The first trailer for Columbia Pictures's Men in Black III is now online.

Following the unveiling of the first posters of Men in Black III earlier this month, our first look at the third chapter a decade in the making is now completed with Columbia Pictures releasing the first trailer online.

Hit the jump to check out Josh Brolin pulling off an almost-perfect Tommy Lee Jones as a young Agent K.



Here’s the synopsis for 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.

Directed by returning director Barry Sonnenfeld and stars Will Smith and Tommy Lee Jones, the film also stars Alice Eve, Emma Thompson, Rip Torn, and Johnny Knoxville. Men in Black III is currently scheduled to release in 3D, 2D and IMAX 3D theaters on May 25th, 2012.
