Is this really a numerical thing?

If I don't use the f-word, but instead have a phrase like "I don't care if he's banging Mother Theresa in the ass...", is this something I can get away with, and keep my pg-13 movie?

What about children who cuss like stevedores?

My rule is "sex, swearing and violence are completely unnecessary - except when they're essential" :-)

Or put another way: if it's all turned up to 11, there's nowhere to go.

The ratings system isn't for writers, it's for viewers. Personally I wouldn't want to sit in a movie with my kids where there was a lot of swearing. If they're going to change the rules they should tell people.

X-Men: First Class used the f-bomb in the best cameo of the year.
