Here come the 'Men in Black...4'! That's right -- as if you weren't expecting it -- a fourth installment of the alien police franchise is coming our way, and if you were thinking this might fizzle out, we've learned that Sony has hired a new writer for the project. So, yeah, it's official.
The Men in Black franchise let us know that Michael Jackson was an alien, and Elvis went back to his home planet. Now in the 3rd installment coming to theaters in May we may find out a logical explanation about Lady Gaga.
It has been almost 10 years since we have heard from K and J, the Men in Black. They will be returning to theaters May 25th. Check out the official trailer for Men in Black 3.
