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.

“We wanted the movie to be both familiar and different,” said director Barry Sonnenfeld, who has taken the helm of all three Men In Black films. “What’s familiar is the characters and premise of the Men in Black and who they are. We wanted to bring Will Smith and Tommy Lee Jones back together again. But we also wanted something new and inventive, and that came in the time travel element.”

The story of Men In Black 3 takes the filmmakers back – back to the characters’ origins, back to the key moments of their relationship, to focus on the key elements that have kept them at arms’ length from each other for 15 years – and looked for ways to resolve the conflict. The answer came in sending Agent J back – back in time to the earliest days of the MIB.

A brand-new MIB adventure, Men in Black International, starring Chris Hemsworth, Tessa Thompson, Emma Thompson and Liam Neeson, is coming to your galaxy in 2019.
