I've seen a lot of discussion pertaining to Ben's Batman voice, but the way he speaks as Bruce Wayne deserves some recognition as well. Normally, Ben has a higher pitch to his voice, but, in the trailer, it comes across more gravelly and emphatic.
I found both his tone and manner of speaking, when talking to Clark, to be fantastic. The smirk response to the initial Clark question is awesome, he just seems to be boiling under the surface which is awesome.
