I very much enjoyed the French movie La Religieuse, based on the late 18th century book by Denis Diderot, better known for his encyclopedia.
The story is about a daughter of lower gentry that gets send to a convent because her parents can't afford her a dowry. She doesn't want to go but is lured in, then refuses to take the vows. But as she brings shame on her family, it is even more difficult to escape the life of a nun and she goes back, more or less of her own free will. Of course she comes to regret it and the movie then documents her struggle to get out.
It was an interesting look at 18th century society, and gives a bit of background to 18th century gaming.
Another French movie I can recommend for this period is Ridicule. In Ridicule, a lowly nobleman travels to Paris to ask the king's aid in financing a project to improve his village. But as the king is bored with audiences the only way to gain access is through the court circuit in which wit and sarcasm provide the means to attract attention.
But of course, you guys want hardcore military history, so my last recommendation is through the Bloggers for Charity, not only a lofty cause, but cleverly combined with the miniature refight of the Battle of La Belle Famille in 1759.
The War That Made America is a four part documentary on the French & Indian Wars and has some interesting combat sequences with reenactors. It is also surprisingly good on introducing the perspectives of Britons, Americans, French and Indians of various persuasions. It takes George Washington's experiences as a main lead, and I see this as inescapable if you consider he was involved in some of the actions and that that is the best way to gain the attention of the general audience.
