In a surprise tie-in, copies of the just-released "Portal 2" include an interactive trailer for the upcoming J.J. Abrams film Super 8. Kotaku has a video run-through of it with a voiceover commentary that you can check out in the player below.

The film, set for release on June 10th, takes place in the summer of 1979, and features a group of friends in a small Ohio town who witness a catastrophic train crash while making a super 8 movie. They soon suspect that it was not an accident and, shortly after, unusual disappearances and inexplicable events begin to take place in town. The local Deputy tries to uncover the truth, which turns out to be something more terrifying than any of them could have imagined.
