Plenty of people batted multiple eyes when Leto was cast, when the film came out, and when he won. And, again, you're ignoring the opportunity differential. Plus the history, same director, same actor. Or are you claiming there are also no Japanese actors good enough to have played the role in GITS?

This is the exact same rationale people have used to cast white people in middle eastern and Asian roles. It has always been bullshit.
