Being old-ish and a bit of an autograph hunter, I've met quite a few. I also work as a film and tv extra for an extra bob or two (will actually be in a film with Natalie Portman later this year for £75 a day wooh - have to wear a bikini though

).
Bill Murray was wonderful - just like you'd imagine him to be. Very friendly yet something shy about him too.
Christine Taylor who is married to Zoolander was beautiful - very radiant and smiley.
Keira Knightly is very quiet. Not rude, but didn't go out of her way to be friendly either.
Steven Spielberg is extremely shy - almost painfully so. He's very hairy and a lot shorter than you'd think. Tom Hanks keeps himself to himself (this was during filming of Saving Private Ryan).
Other peeps I've met - I met Princess Diana at a homeless conference and she looked at me like I was the most important person she had ever seen. Without doubt, she was the MOST charismatic person ever. Her eyes were intense and just entrapped you.
When I worked in the Europa hotel in Belfast I met a few celebs, like Westlife - Kian is the ONLY decent one. The rest sucked. Ronan Keating is horrible - he treated me like I was a piece of rubbish. The guy in Emmerdale - plays Andy - is unbelievably gorgeous in real life. MUCH hotter than he is on the telly. Has a fantastic physique and is a real nice guy to boot.
Kylie is like a dot - I couldn't believe how tiny she is. Like a little doll. Elle MacPherson is gorgeous but not as gorgeous as she looks in magazines.
Iain Duncan Smith is nice for an MP but was a bit of a ladies man and leered a lot which was awkward.
The Corrs are stunning - the one who played the violin lived just up the road from me and cycled everywhere.
Alex Higgins is a rude sh1t..he told me to F off just the other week when I tried to squeeze past him in Tesco.
Matin O'Neill the Villa manager was a real gent - very unassuming and lovely.
Patrick Kielty was a bit ignorant when I met him - thinks he's funnier than he is.
