Black ops....Tommy Lee Jones and Will Smith are back to take on a whole new raft of aliens in 'Men In Black 3'.

Agent J (Will Smith) has seen some inexplicable things in his 15 years with the Men in Black agency, but nothing, not even aliens, perplexes him as much as his wry, reticent partner, Agent K (Tommy Lee Jones).

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 - a journey where J discovers that there are secrets to the universe that K never told him, secrets that reveal themselves as he teams up with the young Agent K (Josh Brolin) to save the future of humankind.

It's been 10 years since the Men in Black were last seen protecting the Earth from the scum of the universe - a return to familiar territory Smith summed up simply as: "You can't beat the black suit."

The story of 'MIB 3' takes us back to the characters' origins, to the key moments of their relationship in a 1960s timeframe. At the beginning of the film, J and K have been partners for 45 years - a fact that makes J wonder what he really knows "about the guy sitting next to me?"

This is the foundation for the story, and one that coincides with the escape of an alien, Boris the Animal (Jermaine Clement), that K put away 40 years earlier, in 1969 - and who's now out for some definite payback.

Boris jumps back in time to 1969 and kills K. But no-one in 2012 has any memory that K wasn't murdered 40 years earlier - no-one except J, that is. To save K (stay with me now), J must follow Boris back into the past and, as he does, meets the younger K (Josh Brolin), a very different version of his longtime partner.

The cast also includes Emma Thompson as O, the new head of the MIB, taking over for the recently departed Zed, Bill Hader as Andy Warhol, icon of '60s art, and Justin Bieber, Tim Burton and Lady GaGa as themselves.

The technical team is equally important in a project of this type, and includes Barry Sonnenfeld in the director's chair, seven-time Oscar winner Rick Baker as the alien designer, and director of photography Bill Pope, who shot the 'Matrix' movies and 'Spider-Man 2 and 3'.

While there are many franchises that have pushed a sequel too far, 'MIB 3' is not one of them. Destined to be one of the early summer hits at the box office, this latest instalment in the series arrives with better aliens, a great script and an even better chemistry between Smith and Jones - who, after all, anchor the entire enterprise.

With Sonnenfeld keeping the action zipping from one outrageous scene to the next, and Rick Baker's outlandish retro '60s alien creations, this is one movie blast worth every cent of your hard-earned cash. No small part of proceedings is Brolin's excellent take on the mannerisms of Jones, right down to mastering that trademark non-expressive gaze of Agent K. A winner.
