Producer Barbara Broccoli told Wednesday's Mirror they are so happy with the new Agent 007, work has already begun on a sequel.
"We're in the early stages," Broccoli said. "It's an original story but it's going to continue part of the story in this film."
"Casino Royale" was Ian Fleming's first Bond book, but the last to become an official Bond screen adventure. Broccoli acquired the film rights to the book in 2000.
