LOS ANGELES (KTLA) -- A 17-year-old student from Michigan traveled to Los Angeles on a mission to change the rating on a movie about bullying.

Katy Butler hand-delivered a petition on Wednesday with more than 200,000 signatures to the Motion Picture Association of America in Sherman Oaks.

She's trying to get the MPAA to change the rating on the documentary "Bully" from R to PG-13.

"The kids who are being bullied need to see it," Butler told KTLA.

"The kids who are the bullies also need to see it, because they can see the direct repercussions of their actions."

The MPAA released this statement about the film: "The R rating and description of some language for 'Bully' does not mean that children cannot see the film. As with any movie, parents will decide if they want their children to see bully."

Meantime, Butler is still hopeful that if people keep signing her petition on Change.org, the MPAA might have a change of heart.

Butler has at least one big-name star backing her campaign to get the rating for "Bully" changed.

She was invited to a taping of the Ellen DeGeneres Show on Wednesday, during which Ellen advocated for the film.

"Last month I got to see a new documentary that's coming out called 'Bully,'" DeGeneres said.

"It's an important movie for everyone to see, especially kids. The problem is, they've given the movie an R rating."

"You can't show R rated movies in schools, and that's exactly where the movie needs to be shown," DeGeneres said. "So I think it's important for the movie to be rated PG-13."

"I have signed the petition," DeGeneres said. "And I hope you will, too." Teen star Demi Lovato has also asked her nearly 6 million Twitter followers to sign the petition.

Please help repeal the R rating on 'BULLY.' EVERYONE should be able to see it. Sign the petition," Lovato tweeted.
