MIB3: Men in Black 3 (Blu-ray)

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 n Black, but nothing, not even aliens, perplexes him as much as his wry, reticent partner. But when Ks 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.
