Because of my job, I've worked with quite a few celebs and they fall into various categories
Complete bumholes full stop:
Samantha Bond (Miss Moneypenny in the Pierce Brosnan's Bonds)
I think it must vary on when you catch some of them.
I met Samantha Bond some years back after seeing her in Macbeth with Sean Bean.
She couldn't have been more friendly & chatted with me for about 20 minutes after the show. I even joked with her that I could be the next Bond when Pierce stepped down I was ex forces, younger, fitter weapons trained & I thought it was long past time Bond & Moneypenny got together. She was really good about it signed my programme & jokingly promised to pass my name on to the produceers for the next Bond movie.
Sadly they gave it to some bloke called Daniel Craig
In any event she was real class.
