As we previously reported, Christopher Nolan headed to Heinz Field, the home of the Pittsburgh Steelers, to film a scene for The Dark Knight Rises. Steelers quarterback Ben Roethlisberger mentioned the shoot on Friday but, as to what would actually be filmed, very few details were out in the open.

While many speculated that the shoot would merely be a backdrop for a Dark Knight Rises character scene with Bruce Wayne, for those in attendance (as Gotham Rogue fans), it quickly became obvious something more substantial was about to happen.

As we’ve previously warned, on-set shooting details can provide MILD to MEDIUM SPOILERS for The Dark Knight Rises. If you are attempting to avoid spoilers altogether, please be advised to turn away now – you have been WARNED.

Still here? Here we go…

There was a lot of inaccurate information coming out of Heinz Field yesterday – most notably, some onlookers claimed that a scene would involve three camouflage tumblers. While the tumblers did appear on the field to entertain the crowd (one was even ridden by Steelers wide receiver Hines Ward) – the vehicles were NOT used for the actual shoot (at least not when the crowd was present).

Check out a video of the tumblers NOT being used for filming below:

Instead, it sounds as though the Heinz Field scene will depict a CGI-heavy interruption of a game between the Gotham Rogues and the Rapid City Monuments – with Bane and his mercenaries arriving at the stadium to set-off a “bomb.” According to an on-scene report, before the set devolved into total mayhem, Bane delivers the line: “Take control of your city… behold the object of your liberation.”

We’ve put together some other highlights below (check out CBM for the full report – though a few of the on-site details have since been debunked) – followed by a gallery of Heinz Field shoot images (thanks again to CBM as well as the Batburgh Facebook page):

– The bane scene was him walking out of the tunnel after the field was blown up. He spoke into a mic he took off a dead referee. He literally sounds like an old man on a respirator. It was hard to make out what he said. Something along the lines of “your city is being liberated…” he had a big object about 5 feet tall, it was a sphere, probably a bomb. Think about the one in the batman movie with two-face at the circus.

– The explosions just happened, couldn’t get a picture bc our section had to run away from it. They just said that the “field will be totally destroyed” and the only part left is the one picture I sent you with the field elevated.

– They are filming the football scene now where the players are running & the field is blowing up. There are holes in that plateau the players disappear into.

Given the dramatic nature of the attack – where Bane suddenly interrupts a life-as-usual football game, it stands to reason that Heinz Field disaster could be used to introduce the villain to the audience (similar to the bank robbery scene in The Dark Knight) – or, at least, introduce the character to Gotham City residents (which could happen a bit later).

The “bomb” was on-set (pictured on the far left in the fifth gallery image) and looked like a five-foot tall globe. That said, it’s unclear whether or not the “bomb” is actually an explosive device or something more advanced (and interesting) – similar to the microwave emitter from Batman Begins. Considering the crumbling Gotham skyline in the Dark Knight Rises teaser trailer and poster – could Bane be harnessing a different element of nature with a Tesla-like electro-mechanical oscillator (earthquake machine)?
