By Egotist / / Principal photography has begun on the highly-anticipated last chapter to Christopher Nolan’s Batman trilogy. And with that, we get art – here is Tom Hardy as Bane: What’s notable about this image is how it was “revealed” – via viral campaign involving audio file visual spectrums and Twitter hashtags. In a nutshell, a hashtag was “discovered” in the visual spectrum for the audio file of the eerie chanting currently on The Dark Knight Rises site. Once fans started tweeting the hashtag, their Twitter avatars began populating the hidden image on the site, and then voila! – Bane is revealed. Simple enough, right? Well, The Dark Knight Rises is set to release July 20, 2012. And we can’t wait… Via.
