Daniel Craig has promised a more human and fallible version of James Bond will be appearing when the latest 007 movie hits cinema screens.
Daniel Craig talks about his vision of the latest James Bond incarnation
But Craig told BBC One's Film 2006 host Jonathan Ross all the traditional Bond elements would be in place.
He will make his debut in the 21st Bond adventure, Casino Royale, which is due out later this year.
Bond producers have faced criticism for their decision to cast Craig, who will be the first blond 007.
Craig, currently on location in the Bahamas, said: "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."
The British star also explained how gruelling chase scenes and fight sequences high up on cranes meant the role demanded a high level of fitness.
He said: "Every day you pick up an injury and you're battered and bruised. If you're not physically fit then it's difficult to get through."
Licence to kill
Casino Royale is based on Ian Fleming's 1953 novel which introduced Bond to the world and explains how he acquires his licence to kill with its 00 prefix.
Craig said he believed there would be plenty to satisfy fans who have grown up watching Connery, Moore, Brosnan and his other predecessors.
He said: "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."
As a lifelong Bond enthusiast who can remember pretending to be 007 in the playground, Craig said he was conscious of the responsibilities of the part.
He added: "Nobody knows more than I do how important this is, and it's my job to get it right."
But one major challenge remains to be faced in the making of a film due in cinemas on 17 November.
Craig has yet to be filmed delivering the classic "Bond. James Bond" line which makes it into every film as a matter of course.
As someone who can remember pretending to be 007 in the school playground, Craig admitted that moment would be "very strange."
Some fans are unhappy over the casting, with the actor's blond hair an apparent bone of contention.
Speaking about the criticism in a different interview, he said: "You can't believe the good stuff. You can't believe the bad stuff. You kind of just take it in. But I'm focused on making this film."
