Gunner Palace
"Gunner Palace" was a PG-13 movie released in 2004, and it has 42 f-words in it. No, I'm not kidding.
Why the heck does that get a pass but this movie doesn't? Seriously, The King's Speech SHOULD be PG-13. No reason for it to be R.
It is, now. When it won Best Picture, they changed the rating to PG-13. I'm not sure what the reasoning was though, since nothing was actually changed in the movie.
I've never seen Gunner Palace, though, so I can't speak to it.
