Morgan Freeman stops by The Tonight Show for an extended conversation with Jimmy Fallon that covers more ground than the average late-night visit. Freeman dismisses the near-universal reverence for his voice, shares the secret to aging that Clint Eastwood passed along to him, and opens up about the true story behind his produced series ‘The Gray House’ and his work narrating Steven Spielberg’s docuseries ‘The Dinosaurs.’ It is the kind of relaxed, candid sit-down that Freeman makes look effortless, which is perhaps the whole point.
