From Diapers to Throne - The New York Times Is there such a thing as a birth vulture? If there is, then that is both the subject and the format of the BBC documentary "Born to Royalty." The film's release this week was timed to coincide with Kate Middleton's due date for the latest heir to the British throne. "Born to Royalty" is an entertaining but light compilation of archival images of the royal family, going back to Queen Victoria, with an ostensible story arc about changing royal parental styles, from the strict upbringing of the stuttering King George VI to Prince William's more casual, affectionate broken home. Commentary is provided by Margaret Rhodes, a first cousin of the queen and the author of "The Final Curtsey"; a former bodyguard of Diana, the Princess of Wales; and a bevy of royal pundits. Revelations include the riveting tidbits that when Queen Elizabeth II was a girl, she lined up her shoes neatly and was crazy about horses. But the attention to, and speculation on, every move of the royal family may seem odd to American audiences, at least to all but the most devoted tabloid readers. With the film's incessant strings and narration by Hugh Bonneville of "Downton Abbey," the earnest yet pompous tone could almost be mistaken for a Monty Python parody of the BBC-standard style. Most comical, however, and also pathetically anticlimactic, is the bold declaration that Prince William might actually change diapers.
