DAVIE, Fla. -

South Floridians from LeBron James to children going to watch "The Dark Knight Rises" are talking about the shootings that took place at a Colorado movie theater early Friday.

James Holmes, 24, is accused of going into a theater in Aurora, Colo., about 12:30 a.m. where "The Dark Knight Rises" was showing, throwing a gas canister and shooting at people. Authorities say 12 people were killed, and dozens more were injured.

Celebrities and politicians hit Twitter on Friday to talk about what happened and express their condolences.

"Its just not fair that innocent people have to lose their lives over someone's selfish stupidity acts! My stomach is hurting over this," the Miami Heat's LeBron James tweeted.

Sen. Marco Rubio sent out a tweet saying, "What terrible news from #Colorado this morning. Praying that God provides comfort to the victims & families and healing to the survivors."

"My prayers are with the families of the victims who lost their lives in this tragic attack in Colorado," U.S. Rep. Allen West tweeted.

Although authorities in Paris have decided to cancel Friday's showing of the movie, at the Cinemark in Davie, all showings were a go Friday.

"You still have to live your life and can't live in fear," one moviegoer said.

The shooting did not spook families from going to the movies. They said what happened is Colorado was so tragically unique that they felt it is unlikely it would happen again.

"Well, of course, you are sort of concerned, but you can't let that stop you. Otherwise, you'll never do anything," another moviegoer said.

One boy, Jacob, told Local 10 the shooting was especially shocking given that it happened in a movie theater, a place where families go and "crime shouldn't be happening."  He's not afraid of going to the movies, he said, just sad for what happened.

Bryan Miller, a grandfather of two, said he worries about how the shooting will affect the quality of life for future generations. He believes his young grandkids won't have the same freedom he enjoyed.

"I'm afraid for these kids when they get older. I got a funny feeling that when they're young adults, you'll probably have to go through a metal detector to go to a movie or a shopping center," Miller said.

AMC Theatres forbid costumes

Movie giant AMC Theatres says it won't be allowing people to wear costumes or face-covering masks into its theaters after the shooting. The Kansas City, Mo.-based company says in a statement on its website Friday that it is "terribly saddened by the random act of violence in Aurora."

AMC said it is working with local law enforcement in communities across the U.S. to review its security procedures. It says on its website it has more than 300 movie houses, making it the nation's second-largest theater chain.

Local 10 placed phone calls with AMC Entertainment, Regal Entertainment and Cinemark to find out what, if any, new security measures may be put in place at theaters across South Florida due to the events in Colorado, as well as if theaters will ban people from showing up in costume. 

So far, Local 10 has not received a call back from any of the theater chains.

The Davie Police Department said Cinemark already had a few off-duty officers in place Friday night for crowd control. The Department said it will not reveal all its tactics for security, but it plans to have extra marked units at some theaters.

Police said there is no specific threat in South Florida.
