I have three that I can think of right now.<br />
When Harry met Sally <br />
The Lake House<br />
and 300 not an obvious choice but at the end when he's dying and he calls out to his wife, it felt so real to me, such a powerful warrior giving everything for the one he loves. Same with Lake House when I thought he died but he was alive in the end I cried so bad. It's just so beautiful.
Lots of them are great; my fav type of movie is a romcom. Some notables: Singin' in the Rain, Valley Girl, Love story, Somersby, Brigadoon (just gotta love musical/fantasy/love stories ;)
an affair to remember .....
