It couldn’t get much more high school than Tuesday’s premiere of “The Gallows” at Hollywood High, where the school’s auditorium was piled with guests jumping in their wooden seats throughout the horror pic.

The film’s stars, Cassidy Gifford, Pfeifer Brown, Ryan Shoos and Reese Mishler, all walked the red carpet in excitement as the film was finally seeing a large theatrical release after being shot nearly four years ago.

“It really feels like we went to horror university and we’re finally graduating and our degree is to finally be at the red carpet in Hollywood,” Mishler said while smiling ear to ear.

New Line bought the found-footage project from Blumhouse Productions and Entertainment 360, the film production operation under Management 360, after they discovered it on YouTube from directors Chris Lofing and Travis Cluff. After reshooting scenes for production value and adding Gifford to the film’s cast, “The Gallows” was set for release on July 10.

Comparable to other teen terrors like Freddy Krueger and Jason, the film’s villain Charlie brings a new meaning to the term “school spirit.” The actors, who all use their real names in the film, assured Variety that their onscreen reactions to the horrific situations were completely realistic.

“The whole movie is improv,” said Shoos. “If I had an idea of something that I wanted to do and not tell Reese about, I would just start talking to Reese and he would start reacting in a natural way.”

There were a lot of real screams emanating from the red carpet, too. Teens surrounded the school as they tried to get pictures and autographs of “Keeping Up With the Kardashians” stars Kris Jenner and Kylie Jenner. The two showed up to support Gifford and snapped photos with her famous mother, Kathie Lee Gifford.

The after-party continued with the back-to-school theme as guests made their way to the Roosevelt Hotel. Guests were given their dinner on a school tray, with burgers, fries and pizza on the menu. One guest said that the only thing missing was the lunch lady in a hair net.
