The definitive, behind-the-scenes look at the most popular sitcom of the last decade, The Big Bang Theory, packed with all-new, exclusive interviews with the producers and entire cast.The Big Bang Theory is a television phenomenon. To the casual viewer, it s a seemingly effortless comedy, with relatable but deeply unique characters tackling real-life issues a kind of visual comfort food for its millions of dedicated fans. But the behind-the-scenes journey of the show from a failed pilot to a global phenomenon is a riveting story that even the most die-hard fans don t know in its entirety. THE BIG BANG THEORY: THE DEFINITIVE ORAL HISTORY is a riveting, entertaining look at the sitcom sensation, with the blessing and participation of co-creator Chuck Lorre and executive producer Steve Molaro, as well as Johnny Galecki, Jim Parsons, Kaley Cuoco, Simon Helberg, Kunal Nayyar, Melissa Rauch, Mayim Bialik, and more. Glamour senior editor Jessica Radloff, who has written over 200 articles on the series (and even had a cameo in the finale!), gives readers an all-access pass to its intrepid producing and writing team and beloved cast. It s a story of on-and-off screen romance told in hilarious and emotional detail, of casting choices that nearly changed everything (which even some of the actors didn t know until now), of cast members bravely powering through personal tragedies, and when it came time to announce the 12th season would be its last, the complicated reasons why it was more difficult than anyone ever led on. Above all else, The Big Bang Theory tackled issues no other sitcoms would touch, which underwent a brilliant metamorphosis during its 279 episodes that mirrored the changing attitudes of America itself. These are the stories shared here, with the intimacy and the reverence the show has earned.
