100 Romance Movies to Watch Before You Die (according to the blog A Love So True)
Here's a trailer for one that isn't on any of the lists, Lost in Austen.
And just for fun, a mashup of Richard Armitage clips, who was once voted most romantic hero (or something to that effect) by a romance writers group. I loved him in the BBC's North and South. I could watch the ending of that movie over and over.
Enjoy your evening, movie or no movie!
