Daniel Craig only realised the importance of audience opinion when he became James Bond.

The British actor never used to worry about what people thought of his career choices until he took on the role of the iconic spy and he knows the films have to do well or the series won't continue.

He said: '''Skyfall' made me remember why I do it. You know, I did a lot of movies before Bond and I used to work because I wanted to work with certain directors and great scripts and I kind of didn't give a f**k what people thought.

''Bond movies live or die on their popularity. They force you to care about what people think. And I'm involved on a very deep level.

''I have it in mind all the time; if it doesn't make any money we're f***ed.''

However, Daniel admits the pressure of success can be an ''enemy'' as he can't afford to have any nerves playing Bond.

He explained to Esquire magazine: ''So there's that kind of pressure, and there's an enemy in any art form, acting especially.

''If you're worried about what people are going to think, then you're kind of nervous. But Bond can't be f***ing nervous. Be relaxed and enjoy it, that's what people want to see.

''They want to see a man enjoy fear, enjoying champagne enjoying martinis, enjoying the fact he's got a beautiful woman.''
