Wonder Woman's first appearance in live-action television was a television movie made in 1974 for ABC. Written by John D. F. Black, the TV movie resembles the Wonder Woman of the "I Ching" period. Wonder Woman (Cathy Lee Crosby) did not wear the comic book costume, demonstrated no superhuman abilities, her "secret identity" of Diana Prince was not all that secret, and she was also depicted as blonde (differing from the image established in the comic books). The film follows Wonder Woman, assistant to government agent Steve Trevor (Kaz Garas) as she pursues a villain named Abner Smith (Ricardo Montalban) who has stolen a set of code books containing classified information about U.S. government field agents.

The pilot aired originally on March 12, 1974 and was repeated on August 21 of that year. Ratings were described as "respectable but not exactly wondrous." ABC did not pick up the pilot, although Crosby would later claim she was offered the series that was eventually given to Lynda Carter. An ABC spokesperson would later acknowledge that the decision to update the character was a mistake and the pilot itself has been labeled one of the "hundred dumbest events in television.
