There is a scene in which Henry's mother is forced into prostitution and we see her enduring some impersonal sex. No nudity, but very sexual and may be disturbing to kids. In a later scene, a group of female prisoners are dressed up for party with some Getmsn soldiers and one women asks a man if she'll have to sleep with him.
Another subplot involves a woman trying to convince a man hiding in her basement to have sex with her.

There is a disturbing violent scene where a group of familes get mowed down by Nazis. And some other violence. I think it would be ok for 12 and up? Depends on the sensitivity of your child.
I don't recall any scenes of sexual activity - clothed or unclothed. I don't think there is any nudity either, but really,why does that matter? The nude body that's just there and not involved in a sex act is not going to psychologically damage your child. I seriously can't wait until this notion that the nude body is immoral becomes obsolete. But we will be all long dead by then.
If you should feel really happy, be patient. It will pass.

Its one of the better version of a familiar story. Belmondo is outstanding.
Its that man again!!

In all honesty I cannot remember how much nudity there is. I think that there is a little bit, but not to much. There is a tiny bit of language. But the main reason that the film is R is because of the violence. Which isn't all that graphic but does show a good amount of blood. Trust me when I say WATCH THIS FILM! It is an amazing and sadly very underrated and almost unknown title.
