In not surprising news, Sam Mendes is moving on from the 007 franchise after Skyfall (2012) and Spectre (2015). Daniel Craig is probably moving on, too, but rumors about who will replace him are, as ever, premature. The names floating about this time are Idris Elba and Tom Hiddleston (wishful fan thinking, maybe, since the internet has been suggesting these two names forever) and 30 year old Jamie Bell which is an interesting idea and probably not a bad one. If chosen he'd be the youngest Bond since Sean Connery (who was 30 when he was cast for Dr. No (1962) though most subsequent Bonds have been around 40 when they started. Plus Bell is super charismatic but underused in cinema.
Though Bond films are largely regarded as producer driven and leading actor focused pictures, rather than directorial feats, the man in the chair is important. In the past the franchise has generally relied on mid level directors rather than auteurs, the two with the most success outside the franchise are Oscar winner Sam Mendes and Oscar nominee Lewis Gilbert. Once the franchise even handed the reigns to a Bond editor who graduated to the director's chair (John Glen) for his directorial debut.

If you could bend producer Barbara Broccoli's ear...
What would you whisper to the woman behind the franchise who makes those final hiring decisions?
