Dennis Lehane is the best-selling author of Boston-based crime novels that have translated well to film (Mystic River, Gone Baby Gone). His first experience with television was on The Wire, a great show that helped inform his new six-part series called Black Birds, which debuts Friday, July 8 on Apple+. It's an incredibly gripping drama and Lehane is happy to talk about it with Leonard and Jessie. You'll learn about the importance of casting not just the leading roles (Taron Egerton, Paul Walter Hauser, Ray Liotta) but every person who appears on camera.
