Christopher Nolan on The Dark Knight Rises attended the event and sat in on the tribute to the director at the Arlington Theatre in downtown Santa Barbara where Nolan said he saw Aliens years ago.

We listened in as moderator Pete Hammond asked where he got the title from and Nolan joked, “I banged my head against the wall.”

The audience laughed and then Nolan went on to say, “We’ve worked on it a long time – David Goyer and myself. We’re about 12 weeks away from shooting. We start in May.”

It’s been known that Nolan wasn’t sure if he was going to do another film or not, so when Hammond asked why he decided to do a third one, he simply said, “It was about finishing the story.”

Nolan still wouldn’t confirm whether Anne Hathaway would play Catwoman or just Selina Kyle. When asked, he smiled coyly and wouldn’t say a word.

The Dark Knight Rises is scheduled to open in theaters on July 20, 2012.

At the same time Nolan will be directing The Dark Knight Rises, he and his wife/producing partner Emma Thomas will also be working on the new Zack Snyder-directed Superman film, which will star the newly-announced Henry Cavill and hits theaters in December of 2012.
