In 2002, Bill Zehme landed one of the most coveted assignments for a magazine writer: an interview with Johnny Carson-the only one he'd granted since retiring from hosting The Tonight Show a decade earlier. Zehme was tapped for the Esquire feature story thanks to his years of legendary celebrity profiles, and the resulting piece portrayed Carson as more human being than showbiz legend. Shortly after Carson's death in 2005 and urged on by many of those closest to Carson, Zehme signed a contract to do an expansive biography. He toiled on the book for nearly a decade, interviewing dozens of Carson's colleagues and friends and filling up a storage locker with his voluminous research, before a cancer diagnosis and ongoing treatments halted his progress. When he died in 2023 his obituaries mentioned the Carson book, with New York Times comedy critic Jason Zinoman calling it "one of the great unfinished biographies."
