Yes, after all they green lighted Men in Black 2. The movie wasn't great, but it made a lot of money. They even have a 3 on the way. At least rumor has it, the movie will be based off a Will Smith and Tommy Lee Jones idea they came up with during 2.
I remember Dan saying that GB3 won't be made for the same reason MIB2 won't be made……
“Always in motion is the future.”
Although, I would hope Dan, Harold, and everyone else get's into shape for the movie.
Side note, how much do you want to bet that John Goodman will be in GB3 if it's green lighted? He's always doing SNL with Dan and vice versa.
