'Catch-22': The True Story Behind George Clooney's New Hulu Series

George Clooney's new miniseries, "Catch-22," is based on Joseph Heller's famous World War II novel of the same name. But what's the true story of "Catch-22"? Heller biographer Tracy Daugherty told InsideEdition.com, "The novel was based very much on his experiences in the military." Heller served as a bombardier in Europe, flying more than 60 missions. Historian Patricia Chapman Meder said, "He was a good soldier. He did what he was told and he did it well."
