"The Dark Knight Rises" director is speaking out about the Colorado theater slayings, calling it a "senseless tragedy" and "devastating." In a statement released Friday night, Christopher Nolan expressed his sadness about the shooting at a movie theater in Aurora. A gunman opened fire on an audience watching a midnight screening of the highly anticipated movie, killing 12 and injuring 59.Speaking on behalf of the cast and crew of The Dark Knight Rises, I would like to express our profound sorrow at the senseless tragedy that has befallen the entire Aurora community. I would not presume to know anything about the victims of the shooting, but that they were there last night to watch a movie. I believe movies are one of the great American art forms and the shared experience of watching a story unfold on screen is an important and joyful pastime. The movie theatre is my home, and the idea that someone would violate that innocent and hopeful place in such an unbearably savage way is devastating to me. Nothing any of us can say could ever adequately express our feelings for the innocent victims of this appalling crime, but our thoughts are with them and their families, the director said. He added that the cast and crew's thoughts are with the victims and their families. "The Dark Knight Rises" is the final film in Nolan's Batman trilogy.Aurora Police Chief Dan Oates said the shooting has prompted increased security.Four theaters in Aurora are showing Dark Knight and until further notice, those theaters will have extra security "out of an abundance of caution," he said.Oates said he is getting calls around the country asking what other police departments should do for theater safety."I don't know what you should do in your theaters, but that's what we're going to do in Aurora for a while," he told reporters on Friday night.
