Good classic love movies?

I mean like love movies like sleepless in Seattle. My friend and I are trying to have a love movie marathon, so we need good classic love movies, but nothing to old or to secular. Also we don't want cheesy high school love movies, like valentines day twilight, those movies are good but not what were looking for. So far on our list is sleepless in Seattle and the notebook, also the proposal. If there are any other live movies you know of that'd be great. Oh, and we love Sandra bullock. Thank you
