It´s always the question of popularity outside of Bond.
Connery was an unknown, so he could become Bond and define the role without baggage.
Lazenby - unknown, but impressive with his arrogance and virility, so he fit the already established profile.
Moore - known, however, only from TV which back then was not taken as seriously as the big screen, and therefore had the potential to break out while bringing in a certain familiarity which was needed to encourage the audience âhey, you know and like him, you can give him a chanceâ.
Dalton - rather unknown, but a theatre actor and reliable, had the potential to become a movie star through Bond.
Brosnan - see Moore.
Craig - rather unknown, but one of these guys the industry was buzzing about, not necessarily regarding lead actor but a talent for edgy tough guy roles.
The next guy - has to be very different from Craig in order to avoid the âoh, heâs just a Craig wannabeâ- criticism. Could be that the pendulum swings back to the âMoore/Brosnanâ-familiarity, but at this point it could also be a total surprise.
Let´s face it: the Bond films are at a crossroads again, with no certain timetable, and after the Craig tenure on wobbly ground. After Craig being ridiculed before CR the PR machine cemented him as THE only Bond for the next generation, so far that many consider him the greatest and irreplaceable. Silly idea, of course. But thatâs where weâre at now.
Therefore, more time passing will be a good thing for the next guy. The hunger for more Bond films must be worked up first. And the next generation must get the feeling that Craig was âyour fatherâs favoriteâ.
As for an established actor taking on Bond - he would bring a lot of preconceptions to the role.
The idea during the late 80´s to get (an already famous) Mel Gibson was problematic because as with every movie star the film would hardly be able to recover from the impression of âOh, this is the one where Gibson / X plays Bondâ.
Also, are there real movie stars now which are not older than 35?
