Its not a prequel, as its set in modern days. But its also not a sequel, as theyre doing Casion Royale, the first novel. Its a reboot, like Batman Begins was.
And to those complaining that it looks like nothing but an action fest, pay closer attention. Youll notice that all the action appears to be from one or two scenes tops. Basically, I think its just a cleverly edited trailer giving off the mucho action vibes, to hook the blockbuster summer movie type fans. I do feel the actual film will be much more of a talkie than the teaser would lead us to believe. If its a faithful adaptation, then there really wont be too much action. Hell, one could say the baccarat game is the major set piece of the story.
No-one else can match that for sheer coolness. But as long as Craig has the same swagger and demeanour I'm a happy film-goer. I buy my ticket to see the Bond persona and it looks like we're going to get it in bucketloads.
