LA CROSSE, WI (WKBT) -

More than 50 Central High School students participated in the production of a movie that shows the negative effects of bullying.

On Tuesday morning, the entire student body watched, "One Voice" for the first time. The movie, which is about 50 minutes long, encourages students to stand up for their friends and be respectful of their classmates.

“It really resonated with me because growing up it wasn’t exactly easy for me,” said Central High School junior Nicole Martin. “I was a tomboyish type girl and never really fit in with the rest of the girls at school.” In the movie, she played the role of Amber, a victim of bullying.

“It brought back a lot of memories. It made me think a lot about how I used to feel and then how kids are still feeling today. It was hard,” Martin said.

Martin and the other students in the movie took three days out of their summer vacation to work on the project in partnership with Haese Productions. The students worked with movie producer Ron Haese to develop the storyline and write the script.

Central High School senior Matt Amann also played a victim of bullying. He said he was happy with the positive reaction from his classmates.

“I definitely hope this film makes a difference,” Amann said. “We put a lot of work into it.”

“Although we have a lot of great students here, there’s some people that definitely need to get some perspective from this movie,” Martin said.

The movie was funded by a grant from Gundersen Medical Foundation's Children's Miracle Network and an AODA grant from the Department of Public Instruction.

In 2009, students at Central High School produced the movie, “Consequences,” which highlighted the dangers of underage binge drinking and driving. In 2012, they produced the movie, “Kickers” on the dangers of misuse of pharmaceutical drugs.
