HOLLYWOOD (KTLA) -- Two major theater chains have canceled showings of the documentary film "Electric Daisy Carnival Experience" after a near-riot broke out outside a Hollywood premiere earlier this week.
Regal and AMC theaters cited "the incident in Los Angeles" for why they will not air the film at any of their locations.
The film is scheduled to be shown in theaters nationwide for one night only -- Aug. 4 at 9 p.m. local time.
People mobbed Hollywood Boulevard for several hours Wednesday after DJ Kaskade made an announcement on Twitter of the film's premiere.
"Today@6pm in Hollywood @Mann's Chinese Theatre. ME+BIG SPEAKERS+MUSIC=BLOCK PARTY!!! RT," Kaskade tweeted.
The tweet brought hundreds of people to the area, causing a mob scene as LAPD officers began turning people away. A section of Hollywood Boulevard was shut down for several hours as the crowd grew unruly.
The premiere of the Electric Daisy Carnival Experience -- billed as the film version of a rave -- was happening at the same location.
The premiere had been promoted for weeks, with an after-party to follow at Supperclub, featuring a performance by Kaskade.
Police say the event was by invitation only, but many people showed up without invites, and were turned away by security.
Authorities say Kaskade did not have a permit for the concert.
The city attorney's office is considering filing charges, the Los Angeles Times reports.
"Our personnel are working in conjunction with LAPD to investigate this incident. Once we receive the files and review everything we will make a determination about whether there was any criminal behavior," John Franklin, a spokesman for the city attorney's office, told the Times.
Kaskade issued a statement to the Times saying he did not mean to cause any trouble.
"I'm incredibly disappointed that last night ended the way it did," the statement read. "It's unfortunate that a few disrespectful people turned what was supposed to be a celebration of music into a regrettable event."
The LAPD shut down Hollywood Boulevard between Highland and Orange avenues after hundreds of people gathered.
Police ordered the crowd to disperse, but many refused to leave, and began fighting and throwing bottles.
Some people jumped on police cars, smashing windows.
About 100 officers in riot gear used bean bag guns to subdue the crowd, and three people -- two men and a woman -- were arrested. LAPD officials say one of the suspects vandalized a police car while another assaulted an officer.
The third person was arrested for failing to disperse.
Some 20 other people were detained for failing to disperse but were eventually released.
No officers were injured.
The Hollywood/Highland Red Line station was closed, and Hollywood Boulevard buses were detoured due to the disturbance.
Kaskade took to Twitter amid the chaos, saying that the party was over and urging people to calm down.
"EVERYONE CHILL NOW!!! The block party has officially been shut down! BUT THIS IS TOO CRAZY AND WE NEED TO BE SAFE!," Kaskade tweeted.
"I AM REALLY CONCERNED FOR EVERYONES SAFETY AT THIS POINT! PLEASE RELAX," he also said.
Finally, he pleaded, "EVERYONE NEEDS TO GO HOME NOW! I DON'T WANT THIS TO REFLECT BADLY ON EDM OR WHAT WE ARE ABOUT. BE RESPECTFUL AND CHILL OUT!!!
Supperclub also posted on its Twitter page, asking people to stay away if they did not have tickets.
"For the safety of our community, DO NOT COME TO SUPPERCLUB tonight. We are grateful for everyone for helping to make this an AWESOME night!"
Insomniac Inc., the organizers of the movie screening, issued a statement saying they were "disappointed that a small group of people would try to mar a private documentary screening."
The Electric Daisy Carnival Experience is a film about the music festival by the same name, which is attended by tens of thousands of people.
It made headlines when a 15-year-old girl died of a drug overdose at the event held in July 2010 at the Los Angeles Memorial Coliseum.
The event was subsequently moved from Los Angeles to Las Vegas.
