For a few brief hours on Tuesday night, it was 2004 all over again in the PAC.  

ASI’s screening of “Napoleon Dynamite,” followed by a Q&A with stars Jon Heder, Jon Gries and Efren Ramirez, attracted lively crowds ready to reminisce on a beloved classic.  

A few attendees sported “Vote for Pedro” shirts, while others rocked a side ponytail. A giant cardboard cutout of Tina the llama in the lobby attracted some families with young children, who posed for photos.

As the movie started, a hush fell over the crowd, which was quickly broken by applause as the opening credits flashed onto the screen.

For the next hour and a half, the audience was fully engaged, laughing along with the classic lines and applauding at key moments, such as Napoleon’s epic dance to Jamiroquai’s “Canned Heat.”

The audience got something of an encore performance of the routine during the Q&A, when one audience member asked Jon Heder how hard the dance scene was to shoot.

“It was nerve-wracking because I didn’t know what I was going to do,” Heder responded, revealing that co-star Tina Majorino helped him rehearse the first piece of the dance the night before filming.

While Gries hummed the music and Ramirez tapped out a beat on the microphone, Heder stood up and performed the first few seconds, to wild applause.

The three cracked jokes throughout the approximately hour-long Q&A, as they received questions ranging from “How did you relate to your characters?” to “What’s the surface area of the moon?” (that one was directed at Gries).

But things also turned warmly serious, as the three actors reminisced on their time on set and noted how many children they see at Napoleon Dynamite screenings now — a sign that the film is being appreciated by new generations.
