The trailer can be a little spoiler-ish. We see more of Catwoman (Anne Hathaway) this time, and the end of the trailer shows her and Batman (Christian Bale) together in one of his bad-ass vehicles. Looks like the two will be teaming up and kicking some ass, as we see in a brief glimpse of them beating up some thugs on a rooftop together. We also hear her say, "you should be as afraid of him as I am." Presumably she is talking to Bruce about Bane (Tom Hardy). So I still think she may start out alongside Bane until she realizes how crazy he is. They also have a heated conversation, with Catwoman telling him "You don't owe these people anymore. You've given them everything." His response: "Not everything. Not yet." That line certainly leaves his fate up to the imagination. I doubt he dies in the end, but some people seem to think he might. I think Batman will "die"(retire), but not Bruce Wayne.
Favorite line - Catwoman: "My mother warned me about getting into cars with strange men." Batman: "This isn't a car." The tumbler then takes off in the air! July 20 can't get here soon enough. Enjoy!
