I don't know; the first international poster and this one are perfectly juxtaposed . . . Batman is looking out at a massive city; the windows mimicking prison bars; it's very metaphorical . . . Batman has created his own prison, and it's this huge, daunting city . . . just look at the scope of it
in this one, it's the diametric opposite; you have Joker in the middle of a street, ready to wreak havoc, and he could be literally anywhere . . . it explains the movie's struggle in a nutshell . . . almost a 'this city's not big enough for the both of us' type showdown feel . . . and about Batman having to find a needle in a haystack . . .
Well said. Both posters are fantastic.
