John Shuttleworth: It's Nice Up North(2006)

Shuttleworth travels to the Shetland Islands to test his theory that the further north in Great Britain you go the nicer people are, Shetland being the most far north part of the UK. He meets various Shetland people in unrehearsed situations. Many assume him to be a real person and not a comic creation, though some scenes are acted, particularly parts with famous local tour guide Elma Johnson.
