Aaron Taylor Johnson is the top contender for the next Bond (report)

To me, he ticks the boxes (age, height, nationality, and masculinity), he's probably the guy they're looking for in Bond 26 and beyond, just watch "Bullet Train".
The only problem is that if Kraven is successful, he might end up being "too famous" for the role.
