Personally, I am a TOTAL historical-fashion junkie, buuut my kids are 8 years and 9 months old, so, while this is an excellent film, I wouldn't let my kids watch it.
There isn't anything too over the top, but because it is a period film ie, things are different/time period appropriate, there are marriage consumations/sex scenes (nothing too graphic) some swearing, lots of drinking, and there is a rape scene about halfway in.
Personally, I think this movie is best suited to young teens 14 to 15 and up.
After I watched the movie I had to know everything about Henry VIII and everyone before and after his reign or related to his life. I have to say the movie is inaccurate in its portrayal of these events. Please do the research for yourself before believing any of the movie.
Aside from that it is a well made movie. With the star studded cast (both actresses are on my top ten list of actresses), the beautiful scenes, and the basic plot were enough to make me want to see it again.
It is not a feel good kind of movie. If you know the story, then you will be ok, but if you do not...well, you'll see. I recommend watching this film. It is very good, just not accurate in its historical portrayal.
Also, do not let kids under the age of 17 see this movie.
It has big stars, gorgeous costumes, and great acting, but any movie with a rape scene should NOT be PG-13. This movie centers on the sexual acts of the King of England with the Boleyn sisters, with one sister scheming to bed him and bear his heir and both doing so. There is plenty of sisterly whispering about sex, many sex scenes, and two seemingly unjust beheadings. Unless a teenager is very mature and able to discuss these themes openly, wait until at least age 16 or 17. This is a good movie, for mature audiences, and one more egregious example of the ratings board's incompetence. It should not be PG-13.
