New York police posted officers at dozens of theaters around the city, while ticket-takers at a multiplex in Washington searched moviegoers' bags and purses.
Security was stepped up at places around the U.S. during showings of the new Batman movie Friday after the massacre in Colorado. And while some people said they were afraid to go to the movies in the wake of the shooting rampage, many others were undeterred by the tragedy and eager to see "The Dark Knight Rises."
Jimmy Baker, 40, waited outside the AMC theater in New York's Time Square for almost three hours to see an early matinee, as a police cruiser sat nearby. "I just felt bad for the people that had to be traumatized by this entire event," he said. But "I didn't feel like it had any kind of effect on me. … I'm just here to enjoy a good movie."
Stephanie Suriel, 21, waiting outside the same theater, said her mother was slightly concerned about her going to see the film. But "I'm not nervous at all because I really want to see that movie."
Still, just to be safe, she said, "I'm going to sit in the back."
In Aurora, Colo., a gunman wearing a gas mask fired into a crowded theater at a midnight opening of "The Dark Knight Rises," killing at least 12 people.
In Washington, the Homeland Security Department held a conference call with officials from the commercial, entertainment and shopping mall industries to discuss what security measures they could take to prevent something like this from happening again.
AMC, one of the nation's biggest theater chains, and the National Association of Theater Owners said they were working closely with law enforcement authorities and reviewing their security procedures, but they gave no details of any precautions taken.
The New York Police Department said was posting officers at about 40 theaters around the city that were showing the film. The increased security was a precaution against potential copycat shooters, and also meant to reassure moviegoers.
"We're doing this to raise the comfort level," Police Commissioner Raymond Kelly said. "We'd certainly encourage everybody to go about their business."
At the Regal Gallery Place multiplex in downtown Washington, moviegoers trickled into an 11 a.m. showing. Theater employees searched patrons' bags and purses while taking their tickets.
"I'm believing that it's not related so much to the movie," Steve Glaude, a 57-year-old federal employee, said of the shooting. "The movie may have been a trigger. It may not have been. We don't know. I don't think it was hero or villain emulation."
Christine Cooley, who works near Tampa, Fla., for the University of Florida., said her 15-year-old daughter has sworn off going to the movies because of the tragedy.
"It's tainted the movie completely for her," Cooley said. "It's summertime. That's a big movie time for teenagers. That movie is off the list now. Movie theaters in general are off her summer to-do list because of that."
Cooley said she tried to explain that the shooting was random and not an indication of security at theaters in general, "but I can see where she's coming from. Why put yourself in harm's way?"
Mark Riggleman, a 22-year-old Ohio State University student, went ahead and saw the movie in Columbus, Ohio, on Friday afternoon.
"I don't want to live my life in fear and not go out to the movies and see something that I really want to see because something like that happens," he said. "If everyone did that all the time, then no one would go out and do anything, and that's not a world I want to live in."
At the United Artists Riverview Stadium 17 in Philadelphia, a steady stream of people headed in for morning showings of "The Dark Knight Rises." Staff members said that there was extra security, but that that was normal for big movies and unrelated to the Colorado shooting.
Neal Mates, 38, a professed "film geek," said: "Shootings can happen anywhere. … I think it's silly to blame the film."
