the credentials of a look-alike nurse. Although the pilot shows Diana briefly as a nurse at one point, Diana instead takes on the identity of a Navy Yeoman Petty Officer First Class (abbreviated YN1 in this article). One change, which was later to become synonymous with the show, was the transformation of Diana Prince into Wonder Woman by spinning. During the filming of the pilot, producers were trying to figure out a way to show how Diana Prince became Wonder Woman, when Carter suggested that she do a spin. Unlike the earlier pilot, the comic-book origins of the character were emphasized by the retention of the character's traditional uniform (the design of which was interpreted and executed by Donald Lee Feld, credited as "Donfeld") with the original setting and through the use of comic book elements.

The sequence in the original specials employed a slow fade between two synchronized shots, both filmed with an overcranked camera to create a slow motion effect. A twirling Diana Prince's hair would fall loose as the shot transitioned
