The rebirth of James Bond since Casino Royale has seen a change in both actor but also the character himself. The suave spy who would chase both woman and bad guys took a more serious tone as well as more of a focus on action and tension. Daniel Craig has brought a new life to the films but the role itself has become almost predictably one dimensional in some cases. Then Skyfall came and some of the wit and brevity of Bond began to seep through and ooze from the role. As we dove deeper into Bond's past we also saw more and more of Bond's personality. It was those moments of comedy that Craig hopes to continue to resurrect from both Skyfall and previous Bond films.
In a recent interview Craig mentioned how he wanted to "reclaim some of the old irony" but hopefully not venturing into imitation. The next bond film, which is being written by John Logan and Sam Mendes who wrote Skyfall as well, will be a direct sequel to Skyfall which would make sense to keep a similar toned Bond in the film. Hopefully the jokes don't venture into cheesy comments which blotted the Connery days of Bond and don't really fit the times. Craig's Bond has always had some biting sarcasm and wit and expanding on that wouldn't be horrible.
