Reader SleepySheep sent us this Pittsburgh news video link; unfortunately it's not embeddable so you'll have to go to the page to view the video. But so far it's some of the clearest footage we've seen yet, of Batman and Bane in the midst of what appears to be a huge brawl between Gotham City cops and Bane's cronies (League of Shadow members perhaps?) on the steps of Gotham City Hall in the midst of a snowstorm. The scale's pretty impressive, and with all that winter gear it's got to be stifling in those outfits in summer.

It's getting pretty difficult to avoid spoilers, although we're still not completely sure what the story is yet. But it's unavoidable for footage like this, considering the size. Judging from the amount of people, I'd say this was from the climax of the film, or close to it.
