That's Naveen Andrews, looking rather badass (and still sporting the Sayid hair) in this scene from "Planet Terror," part of Robert Rodriguez and Quentin Tarantino's double feature collaboration Grindhouse. Judging from the trailer, one can probably expect the usual kind of madness from the minds of these filmmakers.
Speaking of Naveen Andrews, here's a brief story from the Honolulu Advertiser a few weeks back on the Lost actor: 'Lost' actor notes lack of screen time.
He talks about his sorely noticeable lack of screen time in the first part of this season. If you've noticed, the first six episodes focused primarily on Jack, Sawyer and Kate, leaving you to wonder what's going on with everyone else over on the beach. I hope they're not planning on writing off Sayid this season...
