The Simpsons Movie is Rated PG-13...

The MPAA is a trade association, it’s not really so much that they are “worried” about your daughter, it’s what they fear will offend you. In general the MPAA seems to have decided that parents will be more offended if their kid sees boobs in a movie than violence, so movies with boobs get an R rating so unwitting parents won’t complain. The MPAA was probably happy not even doing a rating system, it started doing it because of people complaining about sex and gratuitous violence.

Too much violence can/will get an R rating though, in general graphic violence is always R-rated.

I thought the Irreverent Humor Throughout tag was a joke.

And I saw the movie at the premiere.

Besides the little shots The Simpsons always do… There are a couple of little things that would cause it to get a PG-13 rating.

A couple are:

SPOILER:

For about one second you see Bart’s dick, Marge says “Goddamn”, There are a few more references to sex than they’d ever allow on tv, and Ralph says “I think I like men now!”

So, what you’re saying is that penis ensued?
