Carter's acting career took off when she landed the starring role on Wonder Woman as the title character and her secret identity, Diana Prince. The savings she had set aside from her days of touring on the road with her band[10] to pursue acting in Los Angeles were almost exhausted, and she was close to returning to Arizona when Carter's manager informed her that Joanna Cassidy had lost the part to her. Carter's earnest performance greatly endeared her to both fans and critics and as a result, she continues to be closely identified with Wonder Woman.
