Christopher Guest and Jamie Lee Curtis
Okay, this one's a doozy. The man behind This is Spinal Tap, Best in Show, A Might Wind, and For Your Consideration and his superstar actress wife are Hollywood legends, but did you know that Guest not only holds duel-citizenship in England and the US, but is also a member of British nobility? Guest's formal title is 5th Baron Haden-Guest, and at one point, his family had a seat in the House of Lords. That means Jamie Lee Curtis's full name is Jamie Lee Haden-Guest, Baroness Haden-Guest, and she is a baroness herself. Note: while Guest is on this list of royalty, technically, he's not actually royalty, but part of the peerage. To be considered royalty, you must be related to the royal family somehow, while peers are people who've had noble title bestowed upon them by royalty, but aren't royal themselves. To make it simple, Downton Abbey is about the peerage, The Crown is about royalty.
