In 2019, when the decision was made to conclude the series after twelve successful seasons, there was palpable sadness among fans and crew alike. However, according to insiders, this choice stemmed not only from creative exhaustion but also from a desire to leave while still at the peak of their powers. In a revealing book titled The Big Bang Book, written by New York Times bestselling author Jessica Radloff, details emerged about behind-the-scenes dynamics, confirming that despite occasional disagreements, the overall atmosphere remained positive and supportive.
Audition stories further highlight the serendipity involved in assembling such a talented lineup.
