Yeah, don’t think the next iteration will be as successful, we just had the full reboot and it was good overall, they had a Bond for 15 years allowing the franchise to move forward without much thought.
But, Elba is 51 just now, same age as Daniel Craig was when he did his last filming for Bond, if he got the nod he’d be 53/54 by the time it comes out, a 3 movie deal would mean he’d be nearly 60 by the end of it, not sure what direction they would be moving in with that, but it’s up to the script and the world they create more than anything.
I just don’t see many good candidates who would take it on, Hardy isn’t going to really sign on to this, Cavill is just in too many other things to do this, and the others are a bit off a fresh start, a la Daniel Craig.
