The free screening, held 10 a.m. Saturday at Grove's Pacific Theatres, saw teenage fans and their parents lining up as early as 3:45 a.m, the Los Angeles Times said.
More tickets were handed out than there were seats, a common practice by free advanced screening website, Gofobo.com.
Those who were allowed into the screening were just settling down for the previews when an usher entered the theater warning the audience to stay calm and that some of the guests outside the room were attempting to rush the theater.
“They charged and went straight past the ticket takers for the doors of the actual theater screaming, ‘Let us in! Let us in!' " said a 30-year-old San Pedro, Calif., resident, whose name was not reported. “It took about a half an hour before a police car came with two policemen in it. They started palming kids down and shoving them outside.”
“I’ve been to plenty of premieres and have seen people go crazy over Johnny Depp and Tom Cruise,” said Lizette Van Patten, who took her 13-year-old daughter to the screening. “But nothing like this. Now I’m really convinced that One Direction is like the Beatles of this generation.”
