Lin-Manuel Miranda’s Hamilton has become, as we all know, a gargantuan hit, and the Tony winner stopped by CBS This Morning on April 12 to discuss the tuner and the new book Hamilton: The Revolution, which he co-authored alongside Jeremy McCarter. "I'm really in the words of the show in the 'eye of the hurricane,'" Miranda admitted. "For me the fun of writing this book was it actually gave us sort of a moment to reflect in the making of it." There also came the question of how long the original cast will remain with the production; the show opened on August 6, 2015. "Everyone's contracted for a year and everyone has the the option to re-up. We'll see where we land," said Miranda. Check out the interview below!
