My favorite foreign film is Amelie. It's wonderful and you should see it. It's quite whimsical and enjoyable.
Here is part of the description from Wikipedia because the trailer doesn't do it justice:
Amélie Poulain (Audrey Tautou) is a young woman who had grown up isolated from other children. After the death of her mother and her father's subsequent withdrawal, she developed an unusually active imagination to ward away the feelings of loneliness. Now at the age of twenty-three, Amélie is a waitress at The Two Windmills, a small café in Montmartre that is staffed and frequented by a collection of eccentrics. Having spurned romantic relationships following a few disappointing efforts, she finds contentment in simple pleasures and letting her imagination roam free.
