FairyTale: A True Story (1997)

Based on factual accounts, this is the story of two young girls that, somehow, have the ability to take pictures of winged beings... which certainly causes quite a stir throughout England during the time of the first World War. Everyone, except the girls who think it's quite normal, are excited about this "photographic proof" that fairies exist... even the great Sir Arthur Conan Doyle and Harry Houdini pay the girls a visit.
