Law enforcement officials in New York City said Friday they are beefing up security in response to the shootings, which left at least 12 dead. NYPD Commissioner Raymond Kelly said officers will be at theaters where “The Dark Knight Rises” is playing throughout the five boroughs as a precaution against copycats, and to raise the comfort levels of movie patrons.

A rep for the Indianapolis Police Department told us that while strategies are likely being discussed, there is no immediate plan in place at this time, given that theaters are privately owned.

San Antonio Police Department said at this stage the department had not been brought in on any extended security plans.

The AMC theater chain, the nation's second largest with over 5,000 theaters across the country, said all of  its theaters are reviewing security procedures.

"We are terribly saddened by the random act of violence in Aurora and our thoughts are with the victims and their families. For the safety and security of our guests and associates, we are actively working with local law enforcement in communities throughout the nation and under the circumstances we are reaching out to all of our theatres to review our safety and security procedures," a rep said in a statement. "Being a safe place in the community for all our guests is a top priority at AMC and we take that responsibility very seriously."

FOXNews.com talked to several "Dark Knight Rises" ticket holders, most of whom remained unfazed by Friday morning's mass shooting.

“I actually plan on watching the film today," said Joey Garcia of Texas. "It's terrible what happened but you can't cease to live your life out of fear of what may happen.”

“Even though planes crash all of the time we still travel," said one New Yorker. "Same example can be used across the board.  Who are we as Americans if we let one event affect the way we live!  I bought my tickets a month ago and I’m going at 6pm tonight.”

“I still plan on going," said one 'Dark Knight' fan in Chicago. "One mentally unstable person’s actions have no relation to the film itself. It’s horrible but has nothing to do with the movie.”

“Massacres can happen anywhere and at anytime.  It’s impossible to predict," said Florida resident Geri Guercio weighed in. "I’m not going to avoid public places, especially movie theaters, in fear that something could happen.”

Not everyone was so sanguine. New Yorker Jamie Krauss told FOXNews.com: "It wouldn't affect me seeing the Batman movie at some point, however I wouldn't go into any movie theater this weekend.  I'd be too nervous and looking over my shoulder the whole time."

The shooter, identified as James Holmes, 24, has been arrested. The FBI says there is no indication so far of any links to terror groups.
