"At this point I feel like I got a few more years of running and jumping over stuff before I gotta let the next generation take that," Will admitted.

Will's own son Jaden, 13, seems poised to take the torch from his dad, as they star opposite each other in the upcoming sci-fi film After Earth, but it's Will's 19-year-old son Trey who keeps him on his toes.

"My kids are coming at me a little bit," said Will. "They get that thing where they bump into you at the house ... Right now I'll just clip them every once in a while," joked the Oscar nominee.

The long-awaited third installment of the Men in Black franchise finds Agents J (Will) and K (Tommy Lee Jones) feeling a little too old to battle unwieldy aliens day in and day out. But when history is somehow rewritten and K ceases to exist, J must travel back in time to put things right, literally diving right into 1969 to team up with a younger version of K (played by a pitch-perfect Josh Brolin) to save his partner, the agency, and the future of humankind.

Josh admitted that he couldn't do his impression in front of the Oscar winner.

"I know Tommy," Josh said, comparing the experience to portraying a childhood friend in front of everyone you know.

Although Josh revealed that Tommy hasn't personally given him any criticism on his performance, Tommy told Kevin that he likes what he's seen.

"I think Josh did a good job," Tommy stated simply.
