Men in Black 3 to Feature Retro Aliens

"The thing that's cool is there is a time travel element [to the story]," he says, "Where I had fun is that we go back to the Men in Black headquarters of the '60s. The first thing I said is that we should have retro aliens, not aliens of 2012. More based on B-movies of the '50s and '60s. So, a lot of the aliens are based on that. Space suits with fishbowl helmets and ray guns."

The plot is said to feature Will Smith's Agent J traveling back in time and re-teaming with a younger version of Agent K (Tommy Lee Jones in present day and Josh Brolin in the past). Newcomers to the franchise for the third go-round include Jemaine Clement, Emma Thompson, Nicole Scherzinger, Alice Eve and Michael Stuhlbarg.

Directed by Barry Sonnenfeld, Men in Black 3 hits 2D, 3D and IMAX 3D theaters on May 25, 2012.
