No I don't
Although I do know someone that was an actor on a crimewatch re-enactment.
lol I shouldn't show off, but I was in two of those. I had a big part in the Sally Ann Bowman Crimewatch doc, but it was actually a smaller part in the other for which I was recognised when working in a pub. I couldn't believe it. I wouldn't wanna be famous though.
As for knowing famous people, na, but I am friends with film people and they might become well known at some point.
