Apart from the funeral and the park scenes, the entire shot was at one location, in one house.
Originally, the park scene was suppose to be in the open, but due to the weather, it was moved under a gazebo. Raeline, however, had to ride her bike in the rain, some of which can be seen in the finished product.
Matthew Paine learned how to play the piano specifically for the role in order to play it live. Most of his playing remains in the final product.
