Having written three books about Wall Street and global finance, Michael Lewis knows a thing or two about bubbles. He also has a passion and keen sense for sports, on display in his best-sellers Moneyball and The Blind Side. Does Lewis worry about the world of big-time sports going bust? Not anytime soon. As he explains to Jacob Weisberg, sports have something that people will always crave in their entertainment: unpredictable outcomes.

In the latest episode of Conversations With Slate, Lewis answers a series of questions from our readers, including how he meets the characters in his books and the status of the movie version of Liar’s Poker.

Here’s Part 1 of Lewis’ interview, in which he discusses the challenges of turning Moneyball into a movie. And here’s Part 2, which focuses on repairing the culture on Wall Street. Look for one more segment from the interview in the days ahead.
