It could happen, you never know. Maybe Boris could somehow return (maybe get ressurected) or some new character could be the villian or Agent Jay could turn evil and the film would revolve around Agent Kay trying to liberate him back or... nevermind about suggestions on the plot for the next film but has anyone discovered any hints to a sequel? Like Will Smith hinted about a future MIB film coming up and that he would be happy to appear again as Agent Jay or was he just joking around???
P.S. I wonder whether there will be any new characters other than the villiain and when I say characters I mean Main Characters.
