@spectre All of those actors had never been the main character in a high budget, highly renowned movie. Moore and Brosnan were only famous from TV. Dalton was a Shakespearean actor, Lazenby just faked his way in, Connery had to be trained and prepared for the role as he was a "diamond in the rough". Craig had played a supporting character in Tomb Raider and got noticed because of Layer Cake.
