I get to go to the BAFTA's and IFTA's for the last 5 years so I've bumped into a few celebs. Have never met any really mean or bitchy celebs, unless you include people who work in Irish TV (but I don't count them). Though the weirdest/surrealist meeting would have been with Woody Allen, really nice guy, but super shy. didn't really want to chat about his films, but I mentioned that I had seen him in concert the last time I was in NYC and he smiled and said thanks.
Nicest:
Michael Fassbender - loves Guinness, nicest actor I've ever met. Have met up with him a good few times since in both London and Dublin.
Saorise Ronan - really down to earth and super nice
Jack Nicholson - personification of cool
Jennifer Lawerence - really nice
George Clooney - very nice and chatty about his films, even the bad ones.
Mark Kermode - chatted with him about his BBC Radio 5Live show and his latest book
Nigel Floyd - really nice guy, super knowledgeable about films
Paul Thomas Anderson - Kept to himself, but was nice when I said "hi" to him
Danial Day Lewis - very shy guy, very tall too. but very pleasent.
Hugh Jackman - really nice and chatted to everyone
Christoper Nolan - nice guy to talk to in general but when he talks about film he came across more intense.
Robin Wiliams - chatted more about games then his movies, was saying he was looking forward to BF3
James Cameron - said hi and we fist bumped, told him he was still "king of the world" (Avatar had just came out) and he smiled
Kathryn Bigalow - very nice lady
Russell Crowe - very cool dude, spent about 30 mins talking about Munster taking on the All Blacks in rugby and how he wanted to go the game in Limerick, but didn't know if his schedule would allow him.
Stephen Fry - he's exactly how you think he would be.
Tony Hawk - was really nice and we chatted for about 10 mins about the old Tony Hawk video games.
Ciaran Hinds - fantastic guy, he got a bit tipsy at the awards show and spent most of it on the dance floor
Aidan Gillen - was really nice to chat with.
Colm Meany - loves chatting with him, I kept asking questions about Con Air.
John C McGinley - got really drunk with him and ended up smoking Cuban cigars with him.
Sean Bean - was really cool. Told him that when I was 15 in a school play of The Field that I based my performance on his, and at the time I sent him a letter telling him and he remembered the letter.
Andrew Scott - really cool dude.
I don't usually take pics, but I do have a few on my PC.
