According to Showbiz 411, both Tommy Lee Jones and Will Smith will be back as agent K and agent J for "Men In Black 3" so I guess that kills the earlier rumours that suggested they wouldn't be returning. As if that weren't enough, it was also announced that the third installment will be in 3D! Now this will probably one of the few movies which will be good to watch in 3D, unlike all the recent random movies jumping on the 3D train... *cough*Clash of *cough* the Titans *ahem*.
