The final piece of the Men In Black puzzle has fallen in place and it is with a determination to ignore the lethargic sequel that we welcome the news that Agents Kay and Jay are returning to our screens in the third Men in Black film.

We knew that Will Smith had signed on to Sony’s series about a secret government department to deal with all types of extra terrestrial shenanigans and now Showbiz 411‘s Roger Friedman spoke to the Men in Black behind the camera, director Barry Sonnenfeld, who confirmed that Tommy Lee Jones has signed on as well.

Earlier reports indicated that Josh Brolin was set to play a part in the third film, set for a May 2011 release, potentially as a replacement for Tommy Lee Jones if he didn’t sign on. And with Sacha Baron Cohen and Jemaine Clement the other names thrown into the ring this could be a fun revisiting for the team.

Oh, and if the title didn’t give it away, Sonnenfeld also confirmed it’ll be shot in 3D, because that’s what all the cool kids are doing now. Though after the second film I’m naturally dubious about another movie there was certainly enough in the MIB world, and especially in the great interplay between Messrs Smith and Jones, to make this one worth looking out for.
