I'm impressed at how form-fitting they managed to get the Nite-Owl cowl. Who knows if he can turn his head or not, but if he can, well, then that might be a good way to try a Batman cowl.
The Watchmen trailer is out--even though it Empire took it down, you can DL it
here. Nite-Owl looks cool in it; I was sort of surprised. Doesn't look as stiff as he did in the first picture.
The trailer has determined for me that, following Nolan's films, I will require a Zack Snyder Batman film. DKR is the obvious choice, but a Knightfall or No Man's Land adaptation would rock my socks off, too. Any number of other stories would be great, as well.
