An all-star legal team is taking on the MPAA in an attempt to overturn the R rating assigned to the documentary Bully.

The film, directed by Lee Hirsch, shines a light on America's bullying crisis by following five of the 13 million American children affected by it each year.

Attorneys David Boies and Ted Olsen are were prompted to suggest a lawsuit against the MPAA after learning of the Change.org petition started three weeks ago by Katy Butler, a 17-year-old openly lesbian high school student. The campaign, which aims to drop Bully's rating to PG-13, has garnered the signatures of nearly 450,000 to date, and has drawn the support of celebrities like Ellen DeGeneres, Meryl Streep, Martha Stewart, Demi Lovato, Johnny Depp and  Michael Jordan.

The MPAA's rating was primarily based on a scene in which one bully describes what he will do to a victim, using variations of the F-word, according to the Los Angeles Times . Films that use the expletive at least twice (or only once if used to describe sexual intercourse) almost always receive an R rating.Of the MPAA's decision, Boies says, "How ridiculous and unfair and damaging it is to have a film of this power and importance that is being censored by a rating system that has got simply no rational basis.""You can kill kids, you can maim them, you can torture them and still get a PG-13 rating, but if they say a couple of bad words you blame them. I hope, for heaven's sake, that they find some rational basis before we have to sue them to revise the rating system," he continued.
