I had the same feeling, Caine is already in it, using three of the other main actors in it is a bit overkill IMO
Those are 3 solid, solid actors that will undoubtedly give great performances. No brainer.
Trailer was very decent, Bane really came off as a hulking menace that you don't want to mess around with. It also looks fascinating in the sense of the journey Bruce Wayne/Batman will have to take in this movie. And go figure, I was initially really anti-Ann Hathaway as Catwoman but what I saw in the trailer I liked very much.
And Batman's right. It's not a car.
