The idea for this month's "Men in Black III" was actually born 11 years ago on the set of "Men in Black II," the sequel to 1997's initial sci-fi comedy hit.
As "MIB" franchise director Barry Sonnenfeld recently told CNN, he, along with stars Will Smith and Tommy Lee Jones, was shooting one night, and while they waited on a set repair Smith revealed that he had an idea for the threequel.
"I said 'What,'" Sonnenfeld recalled, "'cause I was tired and there's Will full of energy, joy and happiness."
Smith's pitch, as Sonnenfeld remembers it, went like this: "At the beginning, something has happened and Agent K is missing and I have to go back to the past to go try to save young Agent K. In doing so, myself and the audience find out all sorts of secrets about the world that we didn't even know were out there."
As evidenced by the existence of the third "MIB," Smith was on to something, but at the time all Sonnenfeld could say was, "can we just finish this one?"
They did wrap up "Men in Black II" and are now ready to unveil the third installment - complete with Smith's time travel idea - on May 25. And, if history repeats itself, we just might be in for a fourth film - except with one tweak.
"Will's kind of really smart, but as I said, kind of really annoying, too much energy," Sonnenfeld joked. "When he would get too rambunctious, I would tell him that for 'Men in Black 4,' Will is out and [his son] Jaden Smith is in. ... If we continue on this path, it won't be released until 2032 but it will be damn good."
After all, Sonnenfeld continued, "It all goes into the same pot; it doesn't matter which Smith brings it in. So I am sure he will be fine with it."
Well, not quite. Smith doesn't sound opposed to the idea of a fourth "MIB," but he's not so sure he's ready to pass the torch.
"Jaden is already 13 years old, so he’s at that mythological boys age, you know - it’s time for his bro-mitzvah," Smith said. "So he’s right at that place ... He’s ready to test me so he can’t come anywhere near my movies right now!"
As for Smith's co-star Tommy Lee Jones also sees the potential in a fourth movie.
"It is easy to pick up where we left off," he told CNN. "We know what we are doing, we know how to do it. It's just a hell of a lot of fun."
But if they made a fourth "MIB," would you head out to the theaters to see it?
