The Dark Knight Rises special features footage continues to flow. After finding out how they made the amazing exploding American football field, now we find out how the Tumbler came to be. Seems it was a bunch of Brits that built it, too.
I have to say, if this is the kind of stuff we can expect on the DKR Blu-ray, this might be one to own rather than rent or stream. It was an incredible film in and of itself, but with this kind of great special features content, I'd say this one's a keeper. [Mashable]
