The Los Angeles Police Department was called to a screening of One Direction’s This is Us after eager fans rushed the screen.

According to LA Times , the early screening of the film was held at The Grove’s Pacific Theater. Fans obtained free tickets via gofabo.com and began lining up around 3:45 a.m.- the event was first come, first serve.

Viewers were asked to surrender their cell phones and submit to a security screening before entering the theater. This is Us was slated to begin at 10:00 a.m., but by 10:15, there were still empty seats.

LA Times reports that an usher entered the theater asking everyone to stay calm noting that fans were beginning to rush the theater and that he had called the police. “They charged and went straight past the ticket takers for the doors of the actual theater screaming, ‘Let us in! Let us in!’” explained Lizette Van Patten, one mother who attended the showing with her teenage daughter and her friend. “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.”

Meanwhile a source tells E! News, “It was invite-only with a first-come first serve basis. People that weren't able to get in were stuck outside the theater. Someone shouted that the band was actually there and that's when a bunch of screaming girls ran in and tried to get inside."

This is Us hits theaters August 30.
