Is it just me or does Anthony Daniels seem to be the nicest and most accessible person from the entire Saga? He makes himself available for all sorts of promotions and events and just seems like a genuinely nice fellow. Sure... a lot of people could say that he doesn't have much going on for him besides Threepio so he might as well cash in on him, however, Anthony has had a very long and varied career on his home soil. He is frequently doing television and theatre. Knowing this, I just feel he is a sweet man who understands his fortunes and appreciates his fans.
He has a great (and often self-depricating) sense of humour and appears to be a great conversationalist (with or without the six-million forms of communication).
