Will Smith and Tommy Lee Jones return in their suits for Men in Black 3, and we've got the just-released trailer for you on RadarOnline.com.

In the flick, Smith's character Agent J travels back in time to learn more about Jones's character Agent K, whose younger version is played by Josh Brolin.

Fun fact: The film marks Smith's return to the silver screen in three-and-a-half years, the longest gap in his film career. (His last movie was Seven Pounds, released in December 2008.)
