First you have to know that this is not a real movie trailer. Evidently some people have been fooled by it even though the scenes used are from iconic films and very recent trailers.
That said, this is one of — if not the — best fan trailers for an unreal project I have ever seen. A friend of mine who doesn’t like superhero movies watched it and said “Damn I want to see that film.”
A major hat-tip to betnoir for putting this up on her livejournal.
