London -- British actor Daniel Craig, who won over the skeptics with his dark interpretation of the world's most famous spy in his hit James Bond debut Casino Royale, is set to reprise the role in an as-yet-untitled sequel. "We are rehearsing stunts and I'm throwing myself off tall buildings ... again," he said.

Asked whether "Bond 22" would be based on an Ian Fleming novel, like Casino Royale, he replied: "It's a completely new story and it does go straight on from the end of the last one."
