When we saw photos of M.I.A. shooting this video down in Jamaica a few weeks ago, all the office chatter focused on her outfits and hair. In the photos, Jay Will, director of Voice Mail’s plainly entertaining “Get Crazy,” had Maya in front of a plain wall with a bunch of dudes, so there wasn’t too much else to say. Well, that wall was a greenscreen and Maya touched it up in the edit suite. And now “Boyz” is totally insane. Also, we have dance moves for the next 8,000 years.
