The actor told Film 2006 that his performance in the new adaptation of Casino Royale would show Bond at his most fallible.
Craig explained: "I just wanted to see him make a few mistakes. I want to make the audience believe that it's all going to go wrong and then when it goes right it's much more exciting.
"I'm a Bond fan. If I go and see a Bond movie there are certain things I think should be in it. And they're there. We've got them in spades. Nobody knows more than I do how important this is, and it's my job to get it right."
