This may be a typical featurette without a whole lot of new or interesting information, but I’m intrigued with the film all the same and found it worth watching.
The film is directed by Wally Pfister and, for those who don’t know, he was Christopher Nolan’s cinematographer on The Dark Knight trilogy. That alone should interest you in my opinion. But if that alone doesn’t do it, watch the featurette and tell me you are not intrigued.
