I love the retro aliens in "MIB 3": Will Smith

Smith, who is reprising the role of Agent J in "Men In Black 3 (MIB)", said the USP of this movie is the aliens which are designed keeping in mind the era of 60s.

"The thing I really love is the retro aliens. I thought that was an absolute stroke of genius. The aliens are designed from the science fiction perspective of the 60s. You know, Ray Bradburry, Isaac Asimov, Star Trek on TV," Smith said in an interview.

Rick Baker has designed the aliens with that very awkward, peculiar sense of humor from the 60's sci-fi perspective.

"MIB 3" is shot in 3D and also stars Josh Brolin who plays the younger version of actor Tommy Lee Jones' character agent K.

Sony Picture's will be releasing the film in 3D all over India on May 25.

Talking about the film and why the gap of 10 years between the two series, Smith said, "'Men in Black' is in 3D... It is supposed to be the movie that lives in that kind of world. It adds emotionally, it adds comedically. And it's about time travel, aliens, monsters and most importantly about the relationship between agent J and K! With this film the relation between the two agents grows much much stronger.

"Gap was important because what we had to do was elevate the story, and the only way to do that is to go deeper, deeper into the characters, deeper into the revelations that the movie would reveal."

The film sees Smith go back in time to save the life of his only friend and partner Agent K and save the planet earth from the wrath of criminal alien Borris.

Smith also praised Brolin who plays the character of young agent K.

"There's a certain rapport or repartee that you'll develop with an actor and that becomes your timing, how you create. Josh had studied Tommy so well that there wasn't a single missed beat when Josh came in. It was almost the identical chemistry, which is very difficult to come by," he said.
