Little Lady Fauntleroy (2004)

Former child prodigy James Harries and his family may at first sight seem to be a houseful of geniuses, but although every single member has a Ph.D. in Metaphysics, we soon discover that some were purchased from a fake university in the USA, while the others were awarded to them by themselves. They regard themselves as morally, intellectually, and financially superior to the rest of society, even though the clan (housed in a mock mock-Tudor cottage in the middle of a Cardiff council estate) includes a convicted arsonist, an astral projectionist, a former Bunny Girl, a part-time private detective and a transgender daughter (James is now Lauren), all of whom seem to live their lives in a parallel universe.
