<<The last time I remember noticing an uvular rhotic in a native speaker was in the movie Billy Elliot (which, I believe, is set in Durham). The boy's father uses it several times in the film (particularly noticeable when he's at Billy's audition among RP speakers: "I'm not an expe[R]t")>>
This is actually because of the fact that the boy's father is Scottish and so the pronounciation of the 'r' in 'expert' is quite different to that of standard english
