“Napoleon Dynamite” 8:30 p.m. Sunday, Fox

PASADENA, Calif. — It’s time for the return of “Napoleon Dynamite.”

John Heder has reunited with the entire cast — including Aaron Ruell and “Vote for Pedro’s” Efren Ramirez — to provide the voices for the animated version of the 2004 film. Napoleon Dynamite, and the gang, can be seen when the series debuts with back-to-back episodes Sunday on Fox.

There was talk of making a live-action sequel when “Dynamite” mania exploded, but it never happened.

Heder and Ramirez went on to do other acting work, while Ruell shifted his attention back to his first creative love: photography.

Ruell says that “Napoleon Dynamite” seemed like it was so unique that there would never be another chance to play the roles.

“I was like, that’s OK. It was fun,” Ruell said.

When creator and director Jared Hess made the movie, he was a student who hoped his small film would play well enough at a film festival to help him get an agent and eventually more work.

“We didn’t anticipate at all that we would get into Sundance and then it would get picked up by Fox and then released and that people would like it and all that stuff,” Hess said. “It was all a dream come true.”

Heder didn’t even audition for the role of Napoleon. He was issued a mandate by Hess that he was going to be in the movie.

“I owe everything to the film. I wouldn’t have done all the other things I have done if it hadn’t been in that movie,” Heder said. “I was acting in college and studying animation. If the movie hadn’t happened, I probably would have gone down the road of being an animator.”

Heder first realized the movie was going to huge when it was screened at the Sundance Film Festival and the audience loved it. That was the first time he saw the film with people who weren’t friends, family or fellow film workers.

Sundance wasn’t as big a clue for Ruell. He figured if there was one audience that would embrace the quirkiness of the characters, it would the festival folk. His realization came when the actors had to go through 360-degree body scans to create action figures of their characters.

Ramirez had two “ah-ha” moments.

“There was the first time I saw Denzel Washington wearing a ‘Vote for Pedro’ T-shirt,” Ramirez said. “Then there was the ‘War of the Worlds’ premiere and I met Sir Anthony Hopkins and he was wearing a ‘Vote for Pedro’ button. It was cool to see he had that.”

While many argue “Napoleon Dynamite” is one of the coolest and edgiest movies to be released in the last decade, it contains so little adult material it carries a PG rating. The actors are often stopped by pre-teens who are huge fans.

The actors point to the creators for making “Napoleon Dynamite” seem a lot more risque than it really is. Hess says it’s all a matter of finding ways to do jokes that are based on the characters and their environment.

“For us it pushes us creatively to find ways to do that and feel comfortable while trying to make it real funny but also saying your whole family can watch this and you’re not going to feel like you’ve got to fast forward the TiVo,” Hess said.

That same approach will be used for the return of “Napoleon Dynamite.”
