Yes, there's that as well. The having him stand in the middle of the street with a low-brow and glower was obviously meant to give the trailer an epic feel.

My main problem is how it's obviously gonna be another big morality/philosophy jig. In the original one, they're going on and on about symbols and identity and principles of action--And then fucking up their own moral standards with the ending. Now we hear Alfred giving lectures on basically the same kind of topics and how he's saying Bruce Wayne is obligated to protect Gotham after its apparently developed a dependence on him (utter bullshit).

The only thing I can give credit to Nolan for is his consistency. He knew from the very beginning that these storylines would never fly with the original Batman character since he had a dual identity. Now, with his strictly Bruce Wayne in a Batsuit persona, this little breakdown he's going to have fits Wayne's MO perfectly since the real Batman would be too driven to suffer such a handicap.

To top it off, the Joker isn't choosing to smile and laugh like his definitive character does. His face just got fucked up that way and so he runs along with it; he's not really insane...That is to say, he's not really super-sane. At least Burton had Nicholson lose it after developing his skin-condition.
