I think Daniel Craig just wants to do other stuff. He considers himself a real actor and wants to stretch his muscles. Feeling some burnout.
You look at his imdb page and it is dominated by being James Bond for about 10 years. Movies, video games - he was Bond in the opening ceremonies of the London Olympics.
Good for him, I say. Like in principle. Putting artistic considerations ahead of stacking cash.
That said, I have never been blown away by his amazing chops and wondered what he was capable of. He's respectable sometimes but I have also seen him be quite bad (Dream House). Pretty limited range from what I've seen. But maybe he'll show me something going forward.
