We’ve all squirmed through well-meaning documentaries about civil unrest in foreign countries. So the opening of District 9‘s trailer may have you sighing impatiently at first. But don’t leave for the popcorn yet! These interviewees with South African accents are not only not typical subjects, they’re not human. That said, this mockumentary’s preview withholds more than it reveals — an interrogation scene with an alien utilizes identity-blurring pixelation. Cute, right? Commercial director Neill Blomkamp expanded the story from his short film. Don’t know him from Adam? You’ll probably recognize his producer’s name: Peter Jackson. District 9 has been waging a viral marketing campaign for months now; the trailer is one part of it. And a strong part, too.
