Couple of things today - theres been word doing the rounds that the film currently stands at about 3+ hours[/] long. Obviously they'll be editing that down, theres no way they'll release a 3 hour long Batman film theatrically, but that does suggest a few things. Firstly, you'd guess a lot is going to be happening plotwise in this, you'd have thought given a few things we know and a few things we can guess at. Secondly, it suggests that we're going to be getting a pretty long film regardless, the worry there being that Nolan was teetering on the edge of losing it with TDK for pace, the final boat dilemma tends to divide people as to it's necessity in that film, if he's ended up with a 3 hour film as they go to really edit it down theres a worry the same thing will happen.
Secondly apparently the novelisation has leaked and is doing the rounds, so spoilers ahoy.
