I heard that Vancouver is a place that a lot of movies were made. Could anyone name or recommend me any movies with setting in Vancouver, or with setting in a US city but actually was shot in Vancouver? I'd like a love story movie. I want my friend back in home country to try to find and see it. Thanks!

I need to visit a friend in Nice, France this summer. I know I need to do a lot of searches to compare the prices, but, can anybody show me some short-cuts to save time and energy?
I just need to buy cheapest possible return tickets. Thanks!
