Yeah the initial request for this started on Reddit. Apparently his wife and friend that made the request had gotten him out to see the Hobbit which was supposed to have the extended trailer, but it turned out not to. The friend put the request out on reddit for some way for him to see the trailer or movie. Abrams called Dan's wife the next day. Awesome story.
