PG-13

A lot of stuff in Titanic is G or PG—and there's really not that much swearing, when you compare it to most other contemporary films. Lewis and Fabrizio have some of the more colorful language, but they aren't major characters, and Fabrizio's cussing is all in Italian…so it's a-okay for English-only ears.

That all said, the fact is that you're dealing with the story of a mass tragedy, complete with images of frozen corpses, and so that requires a certain amount of maturity to handle just from the get-go. And then, of course, there's some violence and (brief, and very artistic) nudity.

That's pretty much the extent of the stuff that's likely to give you nerves, the blues, and/or palpitations.
