Always liked the one with the knife-edged throwing hat;
Also the Roger Moore skis over a car film.
Sorry, not as up on my Bond history/titles as some, although I have seen & enjoyed most.
My take on Craig and Casino Royale: I was really upset to see Pierce go, as he was possibly my favorite Bond. I thought he was getting dreadful scripts lately though. The most recent started well with the prison camp, but enough with the Austin-Powers style Uber-Villians.
I LOVE the tone of the new film. Much grittier, more "real", more violent. It could have used some editing though IMO. I enjoyed the plays on some classic Bond gags: "Shaken not stirred", and "Mrs. Broadchest".
I'm not convinced Craig is the only one who could have pulled the film off, but he does certainly do so sucessfully, and any actor in the role is destined to be evaluated packaged with the material production tone they are given. All said, if the choice were Brosnan making films like the last couple Bonds, or Craig making films like the current, I'd take the new all the way.
