Re-casting classic comics characters. - On Comic-Con weekend, we convene to discuss the latest rash of re-casting comic book heroes. Thor is now a woman! Captain America is black! We’re all for increasing diversity in a medium whose classic characters are dominated by white men, but what are the right ways to do it? And are there wrong ways, or does every little bit help? Host Jason Snell with Brianna Wu, Andy Ihnatko, David J. Loehr and Monty Ashley.
