The trailer for Men in Black III has arrived, and thankfully it looks like its capturing everything that was good about the first film and ignoring everything that was bad about the second. The third film sees an alien invasion, a missing Agent K, played by Tommy Lee Jones, Agent J, played by Will Smith, indulging in some time travel, and a new partner in the form of a young Agent K, played by Josh Brolin.

There's a lot going on in this new film, but it looks like the two, or rather the three, have it covered.

Rather than me trying to explain it all again, here's a quick blurb for you:

Agents J and K 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 to save his partner, the agency, and the future of humankind.

Got it? It's certainly going to be a busy film, and the comedy level looks like its just right, if the rest of it lives up to this trailer then I do wonder if there's space for a fourth film.

The trailer features some recognisable moments from the previous teasers, but this one has much more story and action in it, and some more reveals. Here is the Men in Black III trailer from TrailerAddict and you can also see it over at Yahoo Movies:

Who is the man in the prison? Who knew the young Emma Thompson, Agent Oh, was Alice Eve? I just had a look through the cast list and it's pretty big, who knew that Zed was going to be in the film?
