"Warner Bros. and ABC did not give up on the idea, and instead developed another TV film pilot, The New Original Wonder Woman, which aired in November 1975. This film was directed by Leonard Horn and starred Lynda Carter, and its Wonder Woman more closely matched the original character created by William Moulton Marston, down to the World War II setting (Crosby would later claim that she was offered the chance to reprise the role in that film). This second film was more successful and immediately led to production of the series Wonder Woman."
