Says the director:
Download the commentary here.I recorded a commentary track to be downloaded, put on an ipod and listened to in the theater as you're watching Looper. This is an odd thing I tried with Bloom, and have gotten a few requests for it again, so here it is. It is totally different from the commentary track that will be on the Blu/DVD, a bit more technical and detailed. Needless to say, this is NOT to be listened to on a first viewing, or before you've seen the film. Also, please work it so that a glowing screening is never out of your pocket during the movie.
Listen to the introduction before heading to the theater, it has instructions. And lemme know how it works.
