First off, seeing that Christopher Nolan is writing the story, this movie is going to be damn good. I know this thread has been made before, but no one has posted both of the trailers. There's two different trailers with the same video clip but with different voice-overs and speeches. Each trailer has a completely different "speech" in it.
The first voice over
Second voice over
I personally prefer the second one (Russell Crowe's voice-over). But damn, both are good. Which one do you guys prefer? :p
