Actor Will Smith poses at a photo call for Columbia Pictures' "Men In Black 3" at the Four Seasons Hotel on May 3, 2012 in Los Angeles

*Will Smith’s new movie “Men in Black 3” is not only loaded with state-of-the-art special effects that puts the 1997 original  to shame, but its his first-ever film shot in 3D …which he admits gave him pause.

“My first concern with being in 3D was my ears, because I could see these things taking over pretty much the whole of the screen,” Smith told us Thursday during roundtables for the film in Beverly Hills. “When I first saw it and it was cool, I was like alright, we didn’t have me looking like satellite dishes.  And special effects now, you can see anything. Like there are no limitations with special effects.”

Case in point – Tupac.

“That was crazy,” he said of the late rapper’s hologram that performed with Dr. Dre and Snoop Dogg at the recent Coachella Music Festival. “That was like, ‘Whoa! Hey, that’s a little too good. Let’s back that technology off a little bit.’”

Asked if he thought virtual Tupac went too far, Smith said, “No, it was great! But it was so great that it was chilling. That’s the world that we live in now, so it’s just a matter of the artist figuring out how to create it in a way that it’s most effective for the audience.”

Smith says his own audiences are getting younger and younger these days, with much of the fans knowing him as simply Willow and Jaden’s daddy. There are, however, legions of kids around the world who have been introduced to the movie star through reruns of his NBC comedy “The Fresh Prince of Bel Air”

“What’s crazy for me is that ‘The Fresh Prince of Bel Air’ is the biggest thing I’ve ever done,” says Smith. “It’s like I’m the Fresh Prince everywhere I go in the world. ‘El Principe!’ You know, it’s just amazing. A 9-year-old kid in Moscow watching the ‘Fresh Prince’ thinks it’s brand new, so when I show up, it’s as if it’s brand new.  The ‘Fresh Prince’ has been a huge gift for me in that sense.”

But one person’s gift is another person’s embarrassment.  In the audio below, Smith reveals what his kids Jaden and Willow think about him as the Fresh Prince.

“Men in Black 3″ opens on May 25, 2012 in 3D and Imax 3D. Watch the trailer below.
