I don't know how Nolan's fanbase will take this but spokespeople for the director have told The Playlist that not only is there no extended cut of The Dark Knight Rises in existence, nobody has plans for one in the future. Another rumour bites the dust.
That's right – Nolan's film fits just snugly onto an IMAX platter and that's the way he wants it. I suppose it's either a coincidence that his "finished cut" squeezes just inside these limitations or this is an example of restrictions guiding creativity.
Will the deleted scenes ever pop up in isolation? That's a very different question, but I haven't seen many Nolan offcuts turning up on disc so far, have you? The tale of Baby Bane may forever remain a mystery.
