I have to admit this - my favourite is Sean Connery. I know that Connery gets a bad rap for his two films as Bond, but a lot of the anti-Connery sentiment is just because people tend to see David Niven as the definitive Bond. Connery is a great actor, and played James Bond brilliantly - and his voice & accent don't bother me at all.
So, who's your favourite Bond?
(OOC: POD is that the James Bond film series starts earlier, in the mid-50s, with David Niven in the role. Sean Connery is the second James Bond actor, who played the role in two films made in the early '60s.)
