Re-reading IAN FLEMING's James Bond books made movie hunk Daniel Craig broody and miserable - and that was a good thing.
The British stud, who first played 007 in Casino Royale, is back for more Bond in new film Quantum of Solace - and he wanted to portray the darker side of the suave superspy.
Craig recalled reading the books when he was younger and finding Bond a workaholic depressive - and that's the character he wanted to channel in the latest adventure.
He tells Playboy magazine, "I wanted to play around with the flaws in his character. It was much more interesting than having him be perfect and polished.
"I got most of my inspiration from Ian Fleming's books. I reread them. In the books, Bond is suave and sophisticated, yes... but there's also a flawed aspect of Bond.
"In the novels he is quite a depressive character. When he's not working, he's at his worst... I can relate."
