The popular book Perks of Being A Wallflower was adapted for film last year and is due to be released sometime in 2012 by Summit.

But now there’s been a roadbump: The film received a ‘R’ rating from the United States’ MPAA, which alienates many of the potential moviegoers who’ve read the book. So Summit intends to appeal the decision.

Rope of Silicon notes that the film was rated ‘R’ for “teen drug and alcohol use, and some sexual references.”

Larry Richman, a well-sourced movie writer, says the film’s director Stephen Chbosky has intended all along for the film to be rated PG-13.

Would you see the film even if it were rated R? Is it an issue Summit should be concerned with? Parents may not allow their kids to see it.

Emma Watson plays Sam, Logan Lerman plays Charlie, and Nina Dobrev plays Candance.
