I totally agree tdalton. 3 films for each actor will kill the series IMO.
And Stephenson I am not supporting a failed actor unsucessful actor. What I say is choose the right man and dont change it for atleast 5 films. Why say goodbye to a sucessful 007 and look for a new one and take risk. Thats not a clever move I think.
I cant really judge an actor just in 10mins. Sure its important but its not enough. He has to prove many things being Bond is not that easy in my book. And if he really is Bond than why let him go after 3 films?

Not trying to suggest that you were supporting "a failed actor" YOLT; just the opposite I think

Like all of us you no doubt want to see Eon get the best man for the role.
But again, I must disagree with you. Certainly the actor they choose will grow more into the role with each film, that has been true of them all. But whoever the actor is, his first film will be his most important. I think we can all agree that this man has to establish himself as Bond right at the start, or the audience isn't going to come back for film two. Suggesting that the mass of today's audience cares about the Bond franchise enough to look past the film that is front of their face is a little unrealistic. You may want an actor that will deliver 5 good films, but the general audience only wants an actor that can deliver one: the one they're watching.
The Laznby/Connery switch was an odd situation: From everything I've heard, Eon was more than prepared to stay with Lazenby, it was he who decided to leave. Obviously, this left Eon in a panic: I assume they felt very uncomfortable about throwing another new Bond at the audience after only one movie. So they thought the best thing for the franchise was to bring back an established Bond to "stabilize" things. Regardless, this is not the situaion they face now.
I sincerely doubt that Eon is going to be able to attract an actor of any calibre (known or unknown) if they insist he sign on for five films. Moore was obviously the exception, but really, how many good roles were there for a 50 something British actor who had been typecast as an action hero? He knew which side his bread was buttered, and went as long as he could (although not without moments of hesitation). In the end, I don't believe this strategy was particularly good for the franchise. If they try an insist on five films in today's industry, no actor worth having is going to even look at it.
I'm going to stick with three films per actor, four if he is really good as long as he's not starting to get "bored with the part". Two or three years between films (however long it takes to get it right) and 4 years between actors. Keep things fresh, keep the audience hungry, and focus on the film at hand without worrying about any "legacy".
Honestly, I would be happy if after all this wait Eon and co. are able to turn out ONE good movie with a good actor
