Question: is blue valentine based on a true story

Answer: No, Williams was 21 when she received the script and Gosling committed to the production four years later, but filming did not begin until 2009, when Williams was 29, owing to Cianfrance's inability to find financing. The director was also unable to film the ``young'' and ``older'' scenes several years apart as he had hoped, again due to lack of money. The film was to be shot in California but production was moved to Brooklyn, New York and Honesdale, Pennsylvania. Williams wanted to stay close to her Brooklyn home to take care of her daughter, Matilda, so the director chose Honesdale due to its proximity to Brooklyn.
