Christopher Nolan has always been very meticulous about how he releases details for his movies. For The Dark Knight Rises, he's had Warner Bros and their marketing agencies slowly, but surely, unravel the film's plot. If you think about it, all we really know is that the film features Bane's rise to power as Batman returns to Gotham after years away. How the new characters like Miranda Tate and John Blake figure into that story is still not known.
Thankfully, fans may unearth some new tidbits soon as The Dark Knight Rises viral campaign kicks into high gear with a batch of "leaked CIA Bulletins". Wikileaks, anyone? The bulletin features a Dr. Leonid Pavel (who's played by actor Alon Abutbul) and could be providing clues as to how the character fits into the overall story. Is he the one who creates Bane's weaponry? Have a look for yourself.
