After 10 years, Will Smith and Tommy Lee Jones are back for the third installment of the sci-fi comedy "Men in Black."

“Men in Black 3” also stars Josh Brolin, Emma Thompson and Jemaine Clement, with Barry Sonnenfeld returning as director, and Steven Spielberg returning as executive producer.

Premise (from Wikipedia): 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.
