The director of "The Dark Knight Rises" has condemned the shooting rampage at a screening of the film that killed 12 people and injured 59.
Christopher Nolan condemned the shooting as "savage" and "appalling."
"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," Nolan said in a statement on behalf of the cast and crew of the film. "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."
Warner Bros. canceled the movie's Paris premiere, while New York police Commissioner Raymond Kelly said his officers would watch over screenings of "The Dark Knight" in the city to prevent copycat shootings.
AMC Theatres, meanwhile, said it would not permit guests in costumes that make others uncomfortable, nor will it allow face-covering masks or fake weapons.
