I grew up with the great Sir Laurence Olivier, and I think it's fair to say that a lot of actors of my age were influenced by his very individual vocal delivery. He was a showman who would always play to the gallery.
I get a lot of fan mail addressed to Bilbo and sometimes Sir Bilbo - it's hardly ever addressed to Ian Holm, in fact. My business manager drafts the replies, and then I pop in to the office and sign them, 'Bilbo!'
