Folks wondering what Zach Throne has been up to since  graduating from Oxford High School in 2012 can find out by watching the trailer for his first feature film, “Cadia: The World Within.”

It can be viewed on Instagram, Twitter and Facebook by searching under @Cadiafilm.

Response to the trailer has been “really positive,” according to Throne, cofounder and financial director of Just A Skosh Productions (JASP), a film company based in Columbus, Ohio.

“I think a lot of people were excited and ready to see what we were trying to capture (on film),” he said.

Shot in Ohio last summer over a period of 13 days, “Cadia: The World Within” is about three 14-year-old siblings – Matthew, David and Renee Addams – who, after losing their mother, get transported to the mystical realm of Cadia. There, they get caught up in the never-ending struggle between good and evil, represented by the characters Shiloh and Tanion, each of whom leads an army of followers.

The movie is described as a coming-of-age story that explores the concepts of grace, love and doubt. It also examines how folks interact with the world around them and the need for people to believe in each other.

Throne said turning the 88-page script into a 90-minute movie has “definitely been a learning experience.”

“It’s probably been one of the most challenging, but (also) one of the most rewarding experiences I’ve had in my career so far,” he said. “I’m surrounded by a great team and when we hit those bumps in the road, we face them head-on together. And I think by doing that, we’re able to overcome them easily.”

JASP is on track to have a finished product by early spring, so it can be ready for release in late spring or early summer.

“That’s our goal, but at the end of the day, it’s going to depend on what our distributor wants to do,” Throne said.

Another goal is to have a multi-state theatrical release that includes Michigan, Ohio, Indiana, Illinois, Kentucky and Pennsylvania.

“We’ll probably start reaching out to theaters here in the upcoming weeks,” he said.

Working on “Cadia: The World Within” gave Throne the opportunity to collaborate with a couple of well-known names in Hollywood.

One of them is veteran actor Corbin Bernsen, who stars as Grandpa George. Bernsen is best known for his role as opportunistic divorce attorney Arnie Becker on the classic TV series “L.A. Law,” which ran from 1986-94. He’s also known for playing retired cop Henry Spencer on the hit show “Psych” than ran from 2006-14.

How does a small-budget, independent film get an actor like Bernsen?

“As crazy as it sounds, it was (as) simple as just reaching out to his agent,” Throne explained. “They asked for the script. He read it and he was really interested.”

The next thing Throne knew, Bernsen flew to Ohio and spent a day filming. “It was a wonderful experience,” Throne said. “He’s a very honest, humble guy. He’s a hard worker, for sure. “He was really happy to be a part of the project and happy to work with us.”

Bernsen brought a level of “sincerity” to the role that enhanced the film, according to Throne. “When you watch him perform, it’s so real,” he said. “With some actors, you know when they’re acting. You don’t see that with Corbin. It’s pure.”

Off-camera, Throne said Bernsen was not only “a funny guy,” he was a bit of mentor as well. “He was able to give us some advice, which was really valuable,” Throne said.

In addition to acting, Bernsen has written, produced and directed.

The other big name to work on the film was James Phelps, a 32-year-old English actor who’s famous for playing Fred Weasley in the Harry Potter movies.

In “Cadia: The World Within,” Phelps stars as Tanion.

Throne described Phelps as a consummate professional, who was consistently ready to work and “always a joy to be around.”

“I love his dry British humor,” he said.

The film’s budget is just under $50,000. Of that, nearly $12,000 was derived from grants, sponsorships and donations. One of those sponsors was LakePoint Community Church in Oxford Township. Another was Simpson Park Camp in Romeo.

Throne would love to see his film play at the Oxford 7 theater. “It would mean the world (to me),” he said.

He views sharing his work with his hometown as a way to express his gratitude to everyone who supported him during his formative years. He also wants to inspire the current crop of high school students by showing them it’s possible to achieve their goals.
