Today brings photos of Will Smith, Tommy Lee Jones, Emma Thompson, and Nicole Scherzinger on the set of Men in Black III.  James Brolin, Jemaine Clement, and Rip Torn also star, with Gemma Arterton, Alec Baldwin, and Sharlto Copley rumored for small roles.  The plot reportedly revolves around the villain Yaz (Clement) travelling back in time to assassinate Agent Kay, which sets off a chain of events that will destroy the Earth.

The sequel started filming this week in advance of a May 25, 2012 3D release.  Hit the jump to see the images.

Nothing too revelatory (Thompson's MIB agent will wear... a black suit!), save for maybe Scherzinger's Leia-esque hairstyle.  But this is Day 2.  We'll get the juicy looks soon enough.  I'm excited to see Clement in costume as the extraterrestrial Boris, though perhaps the more interesting aspects of his character design will be added in post-production.
