Christopher Nolan is a bit self-conscious. Not that The Dark Knight Rises isn't going to be a worldwide commercial success when it arrives in theaters on July 20, but rather that he wasn't sure how to fit Catwoman into his final Batman movie.

In an interview with Empire via MTV and Screenrant, Nolan says, "Catwoman is a very iconic figure in the Batman pantheon. I was nervous about how she would fit into our world. But [co-writer and brother] Jonathan was very much convinced that there would be a great way to do it and eventually turned me around. Once I got my head around the idea of looking at the character through the prism of our films, saying 'Who could that person be in real life?' we figured it out. She's a bit of a con-woman, something of a grifter. A hard-edged kind of criminal."

Jonathan adds that, "what we're endeavoring to do here is tell a complete take on the Batman mythos. And a complete take of the Batman mythos without the character for me was sacrilegious. You've gotta have her, because she has a delicious greyness to her that helps define who Batman is. She keeps wavering on this line of, 'Is she a good guy or a bad guy?' Well, she's kind of neither. And that's why, to me, that relationship and that character only enhances the universe – and the Batman character."

While the brothers figured out how to work Catwoman into the final movie, writer David Goyer addressed rumors about the possible ending, something some fans have suspected might conclude with the death of the Dark Knight.

"The final scene of The Dark Knight Rises is exactly the scene we talked about when Chris and I started on the trilogy with Batman Begins. It remained completely unchanged. We both knew in our hearts that we were onto something special. I have to tell you, having finally seen everything strung together a little while ago and seeing that scene, I got a complete lump in my throat."

We'll have to wait 52 more days before all the answers spill out onto the big screen. Meanwhile, the posters keep coming. Here are two more unveiled earlier this morning.

Meanwhile, we've been adding these to the Daily Recap posts, but since you've scrolled down this far and are already immersed in the world of the Bat, here are a pair of TV spots which arrived online this week.
