When Free Solo was released last fall, it was an instant sensation—the movie that everyone was telling their friends they had to see. The picture, which won the Oscar for Best Documentary Feature chronicled Alex Honnold’s quest to climb the 3,000-foot sheer rock face ofYosemite's El Capitan without a rope. It also captured his emotional growth as he fell in love with Sanni McCandless, a relationship that made his goal much more complicated. One giant reason Free Solo was so special was the husband and wife directing team of Jimmy Chin and Elizabeth Chai Vasarhelyi, whose unique backgrounds made them the perfect duo to tell the story. In this conversation with Outside’s Michael Roberts, recorded earlier this month at Summit LA, they open up about the life and work that they’ve created together—and where it goes from here.
